Answer:

Slope Intercept Form

y=x-2

Explanation:

Find Slope using equation below


(y2 - y1)/(x2 - x1)

Chose points I chose 2 as y2 and -2 as y2

4 is x2 and 0 as x1


(2 - ( - 2))/(4 - 0) = (4)/(4) = 1

Slope is 1

now choose a point and plug it in for x and y and plug slope in Equation


y = mx + b

I chose (4,2)


2 = 1(4) + b

2=4+b

subtract 4 by both sides

-2=b

Slope Form


y = mx + b

So... y=x-2 is the answer
