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
 one year 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
 one year 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
 one year ago

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

Just isolate the term b
 one year ago

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

 one year ago

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

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