Answer:

y=-5/9x+7

Explanation:

1. Use the two points and plug them into the slope formula to figure out the slope.

y2-y1/x2-x1

2-7/9-0 = -5/9

2. Pick one of the coordinates and use the x and y points and the slope to put them into point-slope form

y-y1=m(x-x1)

y-7=-5/9(x-0)

3. Distribute and simplify.

y-7=-5/9x-0

y=-5/9x+7
