Question

If a line slope is -3/4 then what is the slope of a line which is
perpendicular to the given line.​

Answer 1

Answer:

Possible Answers:

12y−4x=−6

2y−6x=4

3y+9x=2

6y+2x=14

y3−x=3

Correct Answer:

12y−4x=−6

Explanation:

Perpendicular lines will have slopes that are negative reciprocals of one another. Our first step will be to find the slope of the given line by putting the equation into slope-intercept form.

y+3x=7

y=−3x+7

The slope of this line is −3. The negative reciprocal will be +13, which will be the slope of the perpendicular line.

Now we need to find the answer choice with this slope by converting to slope-intercept form.

12y−4x=−6

12y=4x−6

y=412x−612

y=13x−12

This equation has a slope of +13, and must be our answer.

Hope this helps u!!!!!!?
