10-96.

On graph paper, graph a line with slope

Find the equation of the line.

Substitute in the known values for slope

, andto find the-intercept of this line.Now solve this equation for

.Is this line perpendicular to the line

? Explain how you know. The slope of a line (a) perpendicular to another line (b) is the opposite reciprocal of line (b)'s slope.

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