Question

What is the slope of the line that is perpendicular to the line (-4,-3) and (10, 4)?

Answer 1

First need to find the slope of the line with the two points given.

Answer 2

y1-y / x1-x = slopw

Answer 3

4-(-3)/10-(-4) right?

Answer 4

You got it. So what is the slope of that line?

Answer 5

m=7/14
m=1/2

Answer 6

That is correct. Now a line that is perpendicular to that line would have a slope that is the negative inverse of the slope of the original line. Does that make sense?

Answer 7

Yes

Answer 8

So the answer is?

Answer 9

(-1,2)?

Answer 10

The slope of your line is 1/2. The negative inverse of that would be the slope of the perpendicular line. Just reverse the numbers and make it negative.

Answer 11

-2/1?

Answer 12

-2/1 or just -2. Good job.

Answer 13

Thanks!
