H10. Which equation best describes this graph?
The y-intercept of the graph is (0, 3).
This eliminates choices A and E.
The point (0, 3) works in B, C, and D.
23
H10. Which equation best describes this graph?
Try the point (-1, 4) in B.
This eliminates choice B.
Try the point (-1, 4) in D.
This eliminates choice D.
24
H10. Which equation best describes this graph?
Try the point (-1, 4) in C.
Answer C
