What is the slope of a line that is perpendicular to the line that passes through the points (4, 7) and (9, 3)?

Hello Guest!

What is the slope of a line that is perpendicular to

the line that passes through the points P1 (4, 7) and P2 (9, 3)?

m1 $= \frac{y2 -x2}{y1-x1}$

$m1 = \frac{3- 9}{7- 4}$

m1 = - 2

The slope of the perpendicular function is the

negative reciprocal of the slope of the output function.

m2 = - 1 / m1

$m2 = \frac{- 1}{-2} = \frac{1}{2}$

The slope of the perpendicular function is

$m2 = \frac{1}{2}$

Not quite Asinus!  Slope = (y2- y1)/(x2 - x1)

So, slope = (3-7)/(9-4) = -4/5

Hence, slope of perpendicular = 5/4
