Line c passes through points (9, 8) and (6, 4). Line d is perpendicular to c. What is the slope of line d?
To find the slope of line c, we can use the formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the coordinates of the two points we have, we get:
m = (4 - 8) / (6 - 9)
= -4 / -3
= 4/3
Since line d is perpendicular to line c, the slopes of the two lines are negative reciprocals of each other.
Therefore, the slope of line d is -3/4.
