get 2 points and draw aline

extract y from the equation and then find the slope, by comparing the equation with y=mx+c where m is the slope
amistre64
  • amistre64
when x = 0 ; y = 7/3 wne y = 0 ; x = 7/5

Now in the equation put x=0 and find what y is and then do the same for y that is put y = 0 and find what x is
amistre64
  • amistre64
dont need slope with this equation; you could do it, but its extra work
anonymous
  • anonymous
I understand that but if a student asks this question, and if I tell him or her to find the slope, he or she will think on it, and eventually gain a better picture.
anonymous
  • anonymous
Now since you have said that, he will no longer think on it ;)

mathematica to draw a line? in my day we had to walk 10 miles to the nearest store and by a ruler...

i remember back before they invented addition; we used to just lay sticks and stones together....

I remember----even back before that nothing actually existed, and all of on a sudden everything came to existence (I consider this a bad luck)

haha I know. But the only way I learn thins is plotting things and this guy can confirm his/her graph

We perhaps are the reason for the creation, and we tried to create light and unintentionally created darkness, we tried to create matter and created antimatter, we tried to create happiness and created sadness. We only wanted the good things from the creation, but the damned creation told us to create good you need to create bad or evil so as to actually contrast the goodness. I wish it ends now.

We never felt that we can't draw a white line on a white sheet. We only wanted to draw white lines, but had to create a black sheet for the same If the creator would have realized a bit of this before creation; no creation would have ever occured

I didn mean you to feel bad. When I help my friend I used to use graphs. This makes everything clear. And perhaps for us drawing a lines is easy, however for somebody else it can be a big issue. So draws can be helpful to some extent.

is this right lol -3y=5x-7 (0,3),(8,5)

(7.5)

you already have an equation fora line stated, no need to re form it

-5x -3y = -7 is an equation for a line....

  • amistre64
when x=0 (0,7/3) when y=0 (7/5, 0)

7/3 = 2' 1/3 7/5 = 1' 2/5

can u help me
anonymous

Ok lets start again.
anonymous
  • anonymous
i have new equation 2y=5x+11
anonymous
  • anonymous
how do i solve step by step
amistre64
  • amistre64
to find it easily; move the 5x over.. -5x +2y = 11
amistre64
  • amistre64
make x=0 and solve for y 0 + 2y = 11; y = 11/2
anonymous
  • anonymous
How to draw a line. The first thing you have to do is: 1) find the x-intercexion and the y-intersexion. X-interseccion (y=0) -5x+2(0)=11 so x=11/-5
amistre64
  • amistre64
make y = 0 -5x +0 = 11 ; solve for x x = -11/5
anonymous
  • anonymous
does it make sense?
anonymous
  • anonymous
sort of
anonymous
  • anonymous
in order to find Y-Interseccion (x=0), we do the following: -5(0)+2y=11 so y=11/2
amistre64
  • amistre64
thats the easiest way; another way is to get y alone 2y = 5x+11 y = 5x/2 + 11/2 now any number you use for x will make a y and plot the points
anonymous
  • anonymous
11/-5+2y
anonymous
  • anonymous
what you mean by that?
anonymous
  • anonymous
never mind lol
anonymous
  • anonymous
sorry im slow today
anonymous

No problem my friend, we are here to help you. So the final thing (step 2) is to plot the two point we just got. They are: Point1=(-11/5;0) Point2=(0,11/2 ) Plot this two numbers and join them with a line and this is the draw you want. Any question, please ask
anonymous
  • anonymous
its asking for 3 points
anonymous
  • anonymous
a line can be plotted by using just two point.
anonymous
  • anonymous
on this test if i just put two its saying incorrect
anonymous
  • anonymous
grid just goes up to 8
anonymous
  • anonymous
send a picture of the question

  • amistre64
a table of plots can be made using many points :)

hold up k

ok
anonymous

i hope it shows

its not showing
anonymous

hey i took it with my camera why wont it show?
anonymous

dont know. First save it to your desktop and then attach if from there
anonymous
  • anonymous
i did
anonymous
  • anonymous
idk
anonymous

ahhh ok I now know what you want. You have to list different values for x and y isolating y y=(5x+11)/2 now you have to choose values for x, replace them in the last formula and find y. for example. X Y ------- 0 -> 5.5 1 -> 8 2 -> 10.5 the points are: p1=(0;5.5) p2=(1;8) p3=(2;10.5) insert this three point in your graph and you must hopefuly be done :)

  • anonymous
whats the third one down 10 over 2
anonymous
  • anonymous
5 i mean
anonymous
  • anonymous
it means 10.5
anonymous
  • anonymous
you have to move 2 units in the x-direction and 10.5 in y-direction
anonymous
  • anonymous
n the first one is just 0,5
anonymous
  • anonymous
for point 1 you have to move 0 units in the x-direction (no movements) and 5.5 units in the y-direction
anonymous
  • anonymous
Ok I have to go. Hope you are already done with you test
