find the coordinates

Question

Find the equation for the coordinates x₁ = 0, y₁ = -3, x2 = 8 and y2 = -7

Answer 1

(0.-3) and (8,-7) are two points on a line with slope = (-3+7)/0-8) = 4/-8) = -1/2

the line is y=--x/2 + b, solve for b by plugging in either point. (0,-3) looks easier

-3 = b

y=--x/2 -3 is the equation of a line through the two points
