Answer:
B, C, D
Step-by-step explanation:
Subtract 1 from the x-value and see if that's the value you have for y.
A: 1 -1 = 0 . . . . not 2
B: 2 - 1 = 1 . . . yes
C: 4 - 1 = 3 . . . yes
D: -3 -1 = -4 . . . yes
You can also draw a line on the graph with slope 1 and through y-intercept -1. It will pass through points D, B, and C. It will miss point A.
