Answer:
rate of change: 4
initial value: -1
Step-by-step explanation:
The rate of change is the number of units in the y-direction for each unit in the x-direction. As x goes from 0 to 1 (1 unit change), y goes from -1 to 3 (4 unit change). Hence the rate of change is 4.
The "initial value" is the y-value where the graph crosses the y-axis. It is -1, as we observed when computing the rate of change.
