What is the slope of a line perpendicular to the line whose equation is 3x-7y+14=0?

1 answer:

7 0

1. Find the slope of the given line. Do this by solving 3x-7y+14=0 for m:

3x + 14 = 7y, which gives us m = 3/7.

2. Find the slope of a line perpendicular to this one. It's the negative reciprocal of m = 3/7, or -7/3.

▹ Answer

D. 3x² + 13x - 56

▹ Step-by-Step Explanation

(x + 7)(3x - 8) (Using FOIL method)

x * 3x - 8x + 7 * 3x - 7 * 8

3x² - 8x + 7 * 3x - 7 * 8

3x² - 8x + 21x - 56

3x² + 13x - 56
