Find the slope of a line perpendicular to line lt if l(8,-40) and t(0,-7)

The slope of the line perpendicular to LT if L(8,-40) and T(0,-7) is

Solution:

Given, two points are L (8, -40) and T (0, -7).

We have to find the slope of the perpendicular line to the line LT.

Now let us find the slope of the line LT.

We know that, slope of line is given as

Now, slope of LT

We know that, slope of line slope of perpendicular line = -1

Slope of perpendicular line

Hence, the slope of the line perpendicular to LT is

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
