Plot each ordered pair and draw a line. (-4,8) (-2,4) ....
i never did this before im lost
Do you have graph paper?
So, you have to draw the graph? Here is what it should look like:|dw:1378015117111:dw|
I've added a few numbers just to show you the scale.
The first ordered pair is (-4,8) That means to start at the origin and count -4 along the x-axis, then +8 along the y-axis.
|dw:1378015296065:dw| (-4,8) is where the two line intersect.
Do the same for the rest of the points and they should form a straight line.
I suggest you get some graph paper, it will make your life a lot easier.... There are notebooks of graph paper or loose leaf graph paper.
i am trying to see how it will make a line
can you show me another point and maybe i will understand that one
okay i still dont see a line
Graph the rest of the points first.
Do you see the line?
Plot some of the points on the graph that I drew.
is this right
Yes, it is. Keep plotting points.
so the line is straight
Yes it is.
First you should find the pair .... Do it ... Lets answer together !
i think my line is wrong
Find (-4 , 8)=A (-2 , 4 )=B In the system !
i thought we did that already
Draw a system first ! Please ...:)
okay i am new to this so i am having trouble understanding
please help do you mean drawn a line
is that the system
Ok ! Dont need ! always we should have : Y = mX+d First find m : You know m=X/y Ok ?! When you want to find m you shold have two diffrent pair and fhnd them . Then you should be do this : pair1/pair2=m Ok?! Now we have m . Understand this first ?:D
OK ! Very good ! so now we have two different pair in problem ! They re A = (-4,8)&B=(-2,4) OK?!
And now find m :?
i don't understand what this has to do with drawing a line graph
i just have to draw a line graph
Amm ! It s so easyer ! Find the pairs !
so what do we do next
You found them in the last ! Now see this picture :
Exacly its very interesting ! Now take a line from them ! See :
oh i see it finally
i was told the line was straight
It s straight !
this is straight
Yes . In the math Look :
Exacly they are not straight !
