Question

What is the slope of the line perpendicular to the line that passes through (4,7) and (8,9)?

Answer 1

-2

Explanation:

the line that passes trough (4, 7) and (8, 9) has the slope

m= (y2-y1)/ (x2-x1) = 7-9 / 4-8 = -2/ -4 = 1/2

perpendicular lines have their slope negative reciprocal

m= -2 is the slope of the perpendicular line that goes trough the given points
