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

I do! thanks!

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
 2 years ago

3psilon Group TitleBest ResponseYou've already chosen the best response.1
pick either (−2, −2) or (2, 4) to plug in for x and y
 2 years ago

3psilon Group TitleBest ResponseYou've already chosen the best response.1
And you'll be able to solve for the y  intercept b

Ilovemeowmeow Group TitleBest ResponseYou've already chosen the best response.0
so 2=3/2(2)+b? lo

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

3psilon Group TitleBest ResponseYou've already chosen the best response.1
Just isolate the term b
 2 years ago

3psilon Group TitleBest ResponseYou've already chosen the best response.1
b is the y intercept

Ilovemeowmeow Group TitleBest ResponseYou've already chosen the best response.0
So the answer is 1?

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