Slope Intercept Form (Math)

Question

Consider the line -8x-2y=4

What is the slope of a line parallel to this line?

What is the slope of a line perpendicular to this line?

Answer 1

-8x-2y=4

solve for y

-2y = 8x +4

y = -4x -2

parallel lines have slope -4

perpendicular lines have slope 1/4, the negative inverse of -4
