Question

The coordinates of point D are(7,4) and the coordinates of point E are (1,-3). What is the slope of the line that is perpendicular to segment DE? Enter your answer as a simplified fraction in the box

Answer 1

-6/7

Explanation:

The formula for calculating slope is (y2 - y1)/(x2 - x1)

If we plug in these values, then it would be (-3 - 4)/(1 - 7)

If you do the work in parentheses, it would then be -7/-6

Negative divided by negative is positive so it is 7/6

Perpendicular lines have negative reciprocal slopes so -6/7
