Question

Acellus

Find the point-slope equation for
the line that passes through the
points (9,-9) and (-2, 13). Use
the first point in your equation.
y-[?]=[ ](x- [ ])

Answer 1

y+9=-2(x-9)

Explanation:

m=(y2-y1)/(x2-x1)

m=(13-(-9))/(-2-9)

m=(13+9)/-11

m=22/-11

simplify

m=-2

y-y1=m(x-x1)

y-(-9)=-2(x-9)

y+9=-2(x-9)
