Question

Determine which line is perpendicular to y = - 7/5x-2.​

Answer 1

y = 5/7 x - 6

Explanation:

For two lines to be perpendicular, the product of their slope must be -1

The slope of the given function is -7/5

Let the slope of the required function be m

m * -7/5 = -1

7/5 m = 1

7 = 5m

m = 5/7

The slope of the line perpendicular to the line is 5/7

The required equation (using any value of the y-intercept) is expressed as;

y = 5/7 x - 6

Note that the y-intercept value was assumed and any value can be used
