Answer:
y + 4x - 6 = 0
Step-by-step explanation:
Rearranging the given equation:-
4y = x + 24
y = 1/4 x + 6
This has a y intercept of (0, 6) and a slope of 1/4.
Thus, the other line has a slope of -4 and passes through the point (0,6) also.
Using the Point-slope form of a straight line:-
y - y1 = m(x - x1)
y - 6 = -4(x - 0)
y + 4x - 6 = 0 is the required equation
