-3 it’s the rise over run I believe & because it’s going down it’s negative
The equation of the graph of
is (d) on a coordinate plane, an absolute value graph starts at (0, 0) and goes up through (4, 2).
The equation of the graph is represented as:
See attachment for the graph of 
From the attached graph, the curve passes through points (0,0) and (4,2).
Hence, the equation of the graph of
is (d)

Answer:
y = 1/3x - 10/3
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of one another so m = -1/3
Given (-1,-3)
y = mx + b
-3 = -1/3(-1) + b
-9/3 = 1/3 + b
b = -10/3
so y = 1/3x - 10/3
