Question

Consider the line y=2x-7 What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this line?

Answer 1

Answer:

The slope of the given line is 2

Answer -1/2 is the line perpendicular

Step-by-step explanation:

This can be rewritten in fraction form as 2/1 since x/1 = x.

Answer 2

Answer: parallel line = 2x, perpendicular line = -1/2x

Explanation:

In order to have a parallel line:

The slope have to be the same as the original which is 2x

In order to have a perpendicular line:

The slope have to be the opposite reciprocal of the original slope

Which is -1/2x
