What is the slope of a line perpendicular to the line whose equation is x-4y=-12. Fully reduce your answer. no varibles are allowed in the answer. first to answer correctly gets brainliest.

If the equation of a line is y = mx + c, where m is the slope, then the slope of the line perpendicular to this line is -1/m.

We have x - 4y = -12, let’s make it in the form y = mx + c

4y = x+12
y = (1/4)x + 3
The slope of this line is (1/4)

Slope of perpendicular line will be -4

Ithink the answer is b
