Given the graph of a linear function, identify the steps used to find the initial value. Check all that apply.
1 Find the rate of change using rise over run.
2 Find corresponding y values when x = 6, x = 7, and x = 8. Then plot the points to finish the line.
3 Find corresponding y values when x = 2, x = 1, and x = 0. Then plot the points to finish the line.
4 The initial value corresponds to the y value when x = 1.
5 The initial value corresponds to the y value when x = 0.
