Answer:

y = 4x - 59

Step-by-step explanation:

(11, -15) (16,5)

Find the slope:

(-15 - 5)/(11-16)

= -20/-5

= 4

The slope is 4

Find the y-intercept:

y - 5 = 4 ( x - 16 )

y - 5 = 4x - 64

-64 + 5 = -59

The y-intercept is -59

Plug it in the equation:

y = mx + b

y = 4x - 59

Check:

5 = 64 - 59

5 = 5 (correct)

-15 = 44 - 59

-15 = -15 (correct)
