Best ResponseYou've already chosen the best response.1\[slope = \frac{ 4(4) }{ 1(1) }\]

Best ResponseYou've already chosen the best response.1Nope you then need to use this slope and one of the points to find the equation. plug in this formula yy1=m(xx1) (x1,y1) is taken from one of the points

Best ResponseYou've already chosen the best response.1So what do you have so far? m (slope)=4, choose the point (1,4), x1=1, y1=4 you should have y4=4(x1)

Best ResponseYou've already chosen the best response.1Step 1: Find the slope(m) = (4(4))/(1(1)) = 8/2=4

Best ResponseYou've already chosen the best response.1Step 2: Use point slope form to get equation: yy1=m(xx1), m=4, point (1,4) where x1=1, y1=4 In the pointslope equation: y1=4(x4) Do u understand these step so far?

Best ResponseYou've already chosen the best response.1Step 3: Slopeintercept form is y=mx+b So we have y1=4(x4) Solve for y (that is put y by itself on one side).

Best ResponseYou've already chosen the best response.1If you did that correctly you should get: y=4x15
