Consider the line 2x+4y=-4
What is the slope of a line perpendicular to this line?

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

Respuesta :

Slope is -1/2

You can get that by isolating the x by moving it to the other side then divide the y value by the other side.

Perpendicular Slope = 2
Parallel Slope = -1/2
