Answer:
y=-4x+16
Step-by-step explanation:
Okay, so a perpendicular line has an opposite reciprocal slope.
The slope for the first line is x/4, but I like to write it as 1/4x, since it's easier to look at.
The opposite reciprocal for 1/4x is -4x
So far, we have y=-4x+ [ ]
To find the remaining b value, we can use the given point intersection.
plug in the x and y values given (4, -1) and solve for b.
The equation for the perpendicular line is y=-4x+16
