Answer:
A. y = 1, point (0, 1)
B. y = 4, point (0, 4)
Explanation:
You want the y-intercept for each of the two relations shown.
Line A
Setting x=0, we have ...
0 -y = -1
y = 1 . . . . . . . multiply by -1
The y-intercept is 1. The point coordinates are (0, 1).
Line B
Looking for x=0 in the table, we find ...
y = 4
The y-intercept is 4. The point coordinates are (0, 4).
