Question

Please solve for the correct answer. thank you! :)

Answer 1

The first: y = -25x + 180

Explanation:

In every equation b = 170, so

The equation is y =mx + 170

On the line on the graph, for x=2 we have y = 120,so:

120 = m×2 + 170

-50 = 2m

m = 25

Therefore the equation is:

y = -25x + 180
