Write the equation of the line that passes through the points (-8,0)(−8,0) and (9,-3)(9,−3). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.

Find the slope

m = rise/run

m = (y₂ - y₁) / (x₂ - x₁)

m = (-3 - 0) / (9 - -8)

m = -3/17

point slope form is

y = mx + b

plug in m = -3/17 and either point to find b

using point (-8, 0)

0 = (-3/17)(-8) + b

0 = 24/17 + b

b = -24/17

With m = -3/17 and b = -24/17

the equation of the line is

y = (-3/17)x - 24/17 <–––––
