Use the slope formula \[\frac{ y_{2}y_{1} }{ x_{2}x_{1} }\]

But wait that's the slope. You need the y intercept which is the b in y = mx +b

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

Good job! Now we use the slope intercept formula y = mx + b

3psilonBest ResponseYou've already chosen the best response.1
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

3psilonBest ResponseYou've already chosen the best response.1
Perfect! Now just solve for b and you have your answer!

IlovemeowmeowBest ResponseYou've already chosen the best response.0
So the answer is 1?

3psilonBest ResponseYou've already chosen the best response.1
Yes , b = 1 . Do you get it?
