Answer:
y = 4x + 7
or y - 4x = 7
Explanation:
x + 4y = 2
4y = -x + 2
y = -1/4x + 2
The slopes of two perpendicular lines are negative reciprocals of each other. So the slope of the perpendicular line should be negative reciprocal of -1/4, then it is 4
Given m = 4, y = 3, x = -1
y = mx + b
3 = 4(-1) + b
3 = -4 + b
b = 7
y = 4x + 7
