11-102.

Find the equation of the line perpendicular to 5x − 2y = 13 that passes through the point (60, −20). Homework Help ✎

Solve for y so the equation is in y = mx + b form. m = slope (growth)

Subtract 5x from both sides.

−2y = −5x + 13

Divide both sides by −2.

The line perpendicular to the line in the problem has a slope that is the negative reciprocal of the slope of line.

b = 130
