Question

Give the slope of a line perpendicular to the one given.*
15.
y = x -
- 4

Answer 1

-5 is the slope of the perpendicular line

Explanation:

to get the slope of a line perpendicular to another, you usually flip the numerator and denominator of the other line's slope then change the sign, from positive to negative or negative to positive. (every whole number is divisible by one, so if you would want to flip a whole number like 4 it would become 1/4).
