Question

Graph the line 10x + 5y = 20. Then find the slope

of a line that is parallel and perpendicular to the line

Answer 1

You should first of all change the equation from standard form to slope intercept form. The parallel slope should turn out to be -2 and the perpendicular slope should turn out to be 1/2.

Answer 2

I get the slope of the parallel line to be -2 and then 1/2 for the perpendicular one
