Question

What slope would make the lines
perpendicular?
y = -x + 2
y = [?]x – 1

Answer 1

3

Explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

The slope m of a perpendicular line is always the inverse reciprocal.

Therefore, our mperpendicular is 3.

Answer 2

The inverse reciprocal.

The slope of a perpendicular line is always the inverse reciprocal.
