Which choice could be the equation of a line perpendicular to the line represented by this equation? y = 5x− 2a. b.y = 5x +2c. d.y = −5x + 5

5y = -× + c

Step-by-step explanation:

If two lines are perpendicular, the product of their gradient equals -1.

We should note that the general equation of a line is y = mx + c, where m is the gradient.

For the line y = 5x - 2 , the slope is 5. The line that will be perpendicular to this line will have a slope of -1/5.

A line like 5y = -x + c fits the description
