Which line is perpendicular to a line that has a slope of 1/2?

Line having the slope = -2

Step-by-step explanation:

If a line is given with the slope then we have to find a line which is perpendicular to this line.

Let the slope of other line is and this line is perpendicular to the first line.

Then

So

So the line which has slope = -2 will be perpendicular to the line having slope =

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.
