If a line goes through the points (-2,1) and (3,8) what is the slope of a line that is perpendicular to it?

First, you have to determine the slope of the given line and apply the fact that the product of the slopes of two lines that are perpendicular is negative one.

So let us find the slope of the line connecting (-2,1) and

 (3,8)

Recall the formula for finding the slope is

Now, let the slope this line be m, then

We now let the slope of the line perpendicular to it be n, then

Hence the slope of the line perpendicular to it, is

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
