Question

C. Find the equation of the line perpendicular to
y = 14x-5 and passing through (2,-3).

Answer 1

y = -1/14x - 20/7

Explanation:

An equation consists of y = mx + b.

• m = slope
• b = y - intercept

- When a line is perpendicular, the slope becomes the opposite.

14 = -1/14

- Now, that we have the slope, all we need to do is find the y-intercept/b.

y = -1/14x + b

-3 = -1/14(2) + b

-3 = -1/7 + b

-20/7 = b
