Answer: B

Step-by-step explanation:

The equation $y+2=\frac{3}{4} x-8$ is not yet in slope-intercept form( $y=mx+b$ ). Simply subtract 2 from both sides to turn the equation into slope intercept form as $y=\frac{3}{4}x-10$ . For a line to be perpendicular to another, it must have an opposite reciprocal slope. A reciprocal is the fraction reversed, where the numerator is the denominator and vice versa. Thus, 3/4 would become 4/3. The opposite reciprocal of 3/4 would be -4/3.

The slope of the line given is 3/4. Thus, simply plug in the opposite reciprocal of 3/4 for the slope to get: $y=-\frac{4}{3} x+b$ . Then, because the line passes through -12, 1, plug those values in for x and y, respectively.
