  • igloo3000
can you help me with y intercept the slope and the equation though
igloo3000
  • igloo3000
1-4 first
y2o2
  • y2o2
Slope = (-2/3) Y-int = 2 Equation : "y = (-2/3)x + 2"
igloo3000
  • igloo3000
for the first one?
igloo3000
  • igloo3000
can you do the second one
y2o2
  • y2o2
no this is no.4
y2o2
  • y2o2
Ok, i'll solve you the second one
igloo3000
  • igloo3000
wait
igloo3000
  • igloo3000
can you solve 1-4?
y2o2
  • y2o2
No, you have to do them by yourself....i'm just helping.
y2o2
  • y2o2
i'll solve the second
y2o2
  • y2o2
2- Slope = 1 Y-int = 0 Equation: y=x
igloo3000
  • igloo3000
how did you do it?
y2o2
  • y2o2
as you can see, the st.line is passing throw (0,0) this means that the y-int = 0 So the equation is "Y = aX" choose any two points on the graph and substitute with them in the equation let it be (2,2) for example: 2 = a * 2 so a = 1 so the equation is : "y = x"
igloo3000
  • igloo3000
can I solve one then see if I get it right?
y2o2
  • y2o2
yeah , sure
igloo3000
  • igloo3000
thanks
igloo3000
  • igloo3000
wait the y-int that I learned was you always have to put 0 then the number
igloo3000
  • igloo3000
is the answer 1, (0,1), y=x+1?
igloo3000
  • igloo3000
for number 1
y2o2
  • y2o2
No, that's wrong answer
y2o2
  • y2o2
try again
y2o2
  • y2o2
you can get they y-int by letting x=0
y2o2
  • y2o2
y-int is the point of intersection between the St.line and the y-axis
igloo3000
  • igloo3000
is the slope correct?
igloo3000
  • igloo3000
what is not correct?
igloo3000
  • igloo3000
ohh I see
y2o2
  • y2o2
no it's not
igloo3000
  • igloo3000
is the slope -4, the y-int (0, 3 1/2), and the equation y=-4x+ 3 1/2?
y2o2
  • y2o2
actually , the graph is not so clear , so i considered the y-int as (0,3)
igloo3000
  • igloo3000
is everything else correct?
y2o2
  • y2o2
the answer of no 1 will be: Y-int = (0,3) Slope = -3 Equation : "y = -3x+3" *of course this answer is by considering the y-int is 3 not 3.5 or else
igloo3000
  • igloo3000
ok
igloo3000
  • igloo3000
let's keep going!
igloo3000
  • igloo3000
number 3
y2o2
  • y2o2
will you solve it ?!
igloo3000
  • igloo3000
yes
igloo3000
  • igloo3000
and you can check
y2o2
  • y2o2
Ok, go on
igloo3000
  • igloo3000
ok
igloo3000
  • igloo3000
can you tell me the answer so I can check?
y2o2
  • y2o2
no , you tell me your answer
igloo3000
  • igloo3000
ok
igloo3000
  • igloo3000
slope is 1 y-int is (0,-2) equation is y=1x-2
y2o2
  • y2o2
you got the y-int right, but you mistaken the slope
igloo3000
  • igloo3000
it's rise over run
igloo3000
  • igloo3000
found it
igloo3000
  • igloo3000
nope I haven't
igloo3000
  • igloo3000
how do you do slope? cause I know it's rise over run?
y2o2
  • y2o2
yes it's, but in mathematical words...it's change y over the change of x so you just pick any two points e.g : (1,0) & (0,2) [i chose them to only ease the calculations] so the slope = (\[(2-0) \over (1-0) \] which is equal to -2
y2o2
  • y2o2
sorry it's (0-2) not (2-0)
igloo3000
  • igloo3000
is that the answer to number 3 for the slope or is that an example?
y2o2
  • y2o2
yes it's for no. 3
