Question

How do you find the slope perpendicular to `y=3+2 (x-1)`?

Answer 1

Using the general line equation, y = mx + b you put the equation into that form to find the slope, m. Any equation with the inverse slope is perpendicular by definition.

Explanation:

y=3+2(x−1)
y = 3 + 2x – 2
y = 2x + 1

The inverse slope is perpendicular to this line.
