Answer:
Step-by-step explanation:
hello :
the equation is : y = ax+b
the slope is a : a×(1/4) = -1......( perpendicular to a line with a slope of 1/4) because
y=x/4 -2 means y = (1/4)x -2... the slope is : 1/4
but : a×(1/4) = -1 so : a = - 4 y= - 4x+b
the line that passes through (4, -1)
-1 =-4(4)+b
b = 15
the equation is : y = - 4x+15
