Equation for Delta Math

Question

Find the slope of a line perpendicular to the line whose equation is �+6�=−24x+6y=−24. Fully simplify your answer.

Answer 1

slope =-4

= negative inverse of the slope in the equation -24x+4y=-24 or y=4x-6

which has slope= 1/4= the coefficient of the x term when the linear equation is solved for y

take 1/4, flip it upside down and change its sign to get -4/1= -4
