10-96.

Substitute in the known values for slope *x*, and *y* to find the *y*-intercept of this line.

Now solve this equation for *b*.

The slope of a line (a) perpendicular to another line (b) is the opposite reciprocal of line (b)'s slope.

Solve this equation for *y* to find the slope and compare it to the slope of the line in part (a).
