Find an equation for the line that goes through (-3,-16) and (5,8)

Question

find an equation for the line

Answer 1

You have two points. Find the slope from

m = (y₂ - y₁)/(x₂ - x₁)

y = mx + b

Find b using either point and the result for m. For example,

y₁ = mx₁ + b

b = y₁ - mx₁

and you are done.
