Question

Line v passes through points (10, 9) and (1, 13). Line w is perpendicular to v. What is the slope of line w?

Answer 1

9 / 4

Explanation:

The slope of line V can be found using the formula for slope: (y2 - y1) / (x2 - x1).

(y2 - y1) / (x2 - x1)

(13 - 9) / (1 - 10)

(4) / (-9)

Two slopes are perpendicular when the values are reciprocals. The slope of line V is 4 / (-9). The reciprocal of this is: 9 / 4.
