Question

How to find the points of a line that is perpendicular to a line you only know the slope of

Answer 1

the perpendicular slope will be the opposite reciprocal of the original slope .

Explanation:

example: lets use the points (5,3) ( 10,7)

The slope is 5/4

so we need a line of -4/5 (perpendicular) that passes through 5,3

Hope that helps

Answer 2

Write the new equation in slope-intercept form. Replace the old slope with the new slope. Replace the y-intercept's value with a variable (b).
