Use the slope formula \[\frac{ y_{2}-y_{1} }{ x_{2}-x_{1} }\]
Oh do this again? Okay got it hahah
\[\frac{ 4-(-2) }{2-(-2) }\]

Yes . Get it ? :)
I do! thanks!
But wait that's the slope. You need the y intercept which is the b in y = mx +b
oh.
So we found the slope m . Now just plug in One of the two coordinates and the slope into y = mx + b and solve for b. Let me know if you need more help
I need more help forsure
Ok did you find the slope m?
finding it now.
Ok let me know what you get
I got 3/2?
Good job! Now we use the slope intercept formula y = mx + b
pick either (−2, −2) or (2, 4) to plug in for x and y
And you'll be able to solve for the y - intercept b
so -2=3/2(-2)+b? lo
Perfect! Now just solve for b and you have your answer!
how though?!
I just cant find an answer...
Just isolate the term b
b is the y intercept
Is -1=3/2(-2) it?
nope I'll draw it out for you. one sec
ok
|dw:1350673516403:dw|
So the answer is 1?
Yes , b = 1 . Do you get it?
Now that you wrote it out, i get it. thank you!
