Answer:

The answer is

y = (7)/(2)x - 600

Explanation:

Formula:

y = mx + b

We first need to find the slope:

m = (25 - 200)/(50 - 100) = ( - 175)/( - 50) = (7)/(2)

Now we need to find the y-intercept:

y = mx + b (substitute)

100= 7/2(200) + b

100 = 700 + b

-700=-700

-600 = b

Using the information we now have:

$y = (7)/(2)x \: - 600$
