Answer:
HAEC
Explanation:
You want the code letters associated with lines 1–4 on the graph.
Line 1
Has a y-intercept of -4, and a rise/run if 1/4. The equation is ...
y = 1/4x -4 (H)
Line 2
Has a y-intercept of -4, and a rise/run of 4/1 = 4. The equation is ...
y = 4x -4 (A)
Line 3
Has a y-intercept of 3, and a rise/run of -2/1 = -2. The equation is ...
y = -2x +3 (E)
Line 4
Has a y-intercept of +1 and a rise/run of 2/1 = 2. The equation is ...
y = 2x +1 (C)
The code is HAEC.
