Find the rate of change and the initial value of the linear function given as a table of values.
(1 point)
The rate of change is m=
, and the initial value is b=
The rate of change is m = (change in y) / (change in x) = (8 - 4) / (-3 - 1) = 4 / (-4) = -1.
The initial value is b = y - mx = 4 - (-1)(1) = 4 + 1 = 5.
