Question

The lines shown below are parallel.if the green line has a slope of -1/2, what is the slope of the red line?

A.2
B.-1/2
C.-2
D.1/2

Answer 1

The anwser is D

because it is very easy

Answer 2

The slope of red line is
`-(1)/(2)`

B is correct.

Explanation:

Two lines are parallel. Two lines shown by color green and red line.

As we know if lines are parallel then their slope is equal.

W are given green line is parallel to red line.

The slope of green line is
`-(1)/(2)`

But The slope of red line = slope of green line.

Slope of red line
`=-(1)/(2)`

Hence, The slope of red line is
`-(1)/(2)`
