Question

Find the slope that is parallel to the equation 2x +3y 15

b) Find the slope that is perpendicular to the equation 2x + 3y 15​

Answer 1

a) -2

b) 1/2

Explanation:

2x + y = 15 Subtract 2x from both sides

y = -2x + 15 The slope is -2

Parallel lines have the same slope.

Perpendicular lines have negative inverse slopes.

-2 flips to 1/2
