Question

Find the slope of the line that passes through the points (4,1) and (-2.7).

What is the slope of a line perpendicular to this line?

Answer 1

the slope=-1 the slope perp=1

Explanation:

to find slope perpendicular you just have to multiply your slope by something and have it equal -1

for example

1/2x=-1

the slope perpendicular to a line with the slope of 1/2 would be -2 beacause 1/2x-2=-1

so the slope x perpendicular slope = -1
