10-160.

Find the equation of the line that is perpendicular to y = x − 3 and passes through the point (10, 14). Homework Help ✎

What is the slope of the perpendicular line?
Recall thatperpendicular slopes have a product of −1.

If you use y = mx + b, use the given (x, y) point to solve for b.

y = −2x + b
14 = −2(10) + b
