Question

Need help with this problem​

Answer 1

1/4

Explanation:

The slopes of two perpendicular lines are negative reciprocals of each other.

Perpendicular slope =
`(-1)/(m)`

The slope (m) of the green line is -4.

To solve the slope of the red line, substituted -4 into the equation:

`(-1)/(-4)`

Solve:

`(-1)/(-4)` which give you
`(1)/(4)`

Answer 2

¼

Explanation:

m1 × m2 = -1

m2 = -1 ÷ -4

m2 = 1/4
