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* = −2*x* + *b*

14 = −2(10) + *b*
