Answer:

y = -3/4x + 1.25

Explanation:

1. Find the slope of those coordinates: which is -9/12 then simplified to -3/4

2. apply into the point-slope formula (y - y1 = m(x-x1)) and you will get

y -5= -3/4(x+5)

distribute: = -3/4x - 3.75

then +5 to get rid of it

y - 5 = -3/4x - 3.75

+ 5 + 5

--------------------------

y = -3/4x + 1.25
