Question

Which equation represents a line which is perpendicular to the line y=-\frac{1}{8}x+3

Answer 1

An equation with -8 as the slope.

Explanation:

I can't see your choices but you need to look for an equation in which the slope is -8. A line with an opposite reciprocal slope is needed in order to be perpendicular to the line y = 1/8x + 3. The opposite reciprocal of 1/8 is -8.
