Answer:
y = -1/3 x + 1/3
Step-by-step explanation:
The red line passes through points (0, 2) and (2, 8).
The slope of the red line is (8 - 2)/(2 - 0) = 6/2 = 3
The slope of the perpendicular line is -1/3, and it passes through point (1, 0).
y = mx + b
y = -1/3 x + b
0 = (-1/3)(1) + b
b = 1/3
y = -1/3 x + 1/3
