Best ResponseYou've already chosen the best response.1But wait that's the slope. You need the y intercept which is the b in y = mx +b

Best ResponseYou've already chosen the best response.1So 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

Best ResponseYou've already chosen the best response.1Good job! Now we use the slope intercept formula y = mx + b

Best ResponseYou've already chosen the best response.1pick either (−2, −2) or (2, 4) to plug in for x and y

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

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