Question

Which of the following is rhe equation of he line rhat is perpendicular to y=-1/8x-2and it gose with the point (-2,-3)

Answer 1

y = 8x + 13

Explanation:

I'll assume you mean y = (-1/8)x - 2, which has a slope of -1/8. Any line that is perpendicular to y = (-1/8)x - 2 must have a slope of 8, which is the negative reciprocal of (-1/8).

Using the slope-intercept formula y = mx + b, and letting y = -3, x = -2, and m = 8, we get this formula for b:

-3 = 8(-2) + b.

Thus, 13 = b, and the desired equation is

y = 8x + 13
