Question

Solve the following equation for y, and then identify the slope of the line: 9x-3y=15

Answer 1

$9x-3y=15\ \ \ | subtract\ 9x\\\\ -3y=-9x+15\ \ \ | divide\ by\ -3\\\\ y=3x-5\\\\ y=ax+b\ \ a-\ slope\\\\ a=3\\\\Slope\ is\ equal\ to\ 3.$

Answer 2

9x-3y=15
-9x       -9x
-3y=-9x+15
/-3     /-3

y=3x-5

slope=3
