Question

Find the slope of the line perpendicular to the line containing (0,0) and (-1,4).

Answer 1

Answer:

Hello, Have a good day

Step-by-step explanation:

The slope of the perpendicular line is the opposite sign and the inverse of the original line's slope.

(-1,-2) and (0,0).

slope = (0 - -2)/(0 - -1) = 2/1

So ,inverse and opposite would be -1/2

A parallel line has the same slope with a different y intercept

-2 = (-1/2)(-1) + b

-2 = 1/2 + b

b = -5/2

So, same slope, different b (y intercept) for a parallel line.
