y + 1 = 4x
y = 4x -1
so slope = 4
perpendicular lines, slope is opposite and reciprocal
so slope of perpendicular line = -1/4
line 2x + 3y = 6
y intercept when x = 0 so 3y = 6 then y = 2
So now perpendicular line , slope= -1/4 and y-intercept b = 2
equation
y = -1/4x + 2
4y = -x + 8
x + 4y = 8
answer
C. x + 4y = 8
