To find the initial value, we need to find the y-intercept of the linear function. The y-intercept is the value of y when x = 0. In this case, the point (0, 1) is on the graph, so the initial value is 1.
To find the rate of change, we use the slope formula. The slope is the change in y divided by the change in x. The points (-3, 2.5) and (0, 1) are on the graph, so we can use these points to find the slope.
slope = (change in y) / (change in x)
slope = (1 - 2.5) / (0 - (-3))
slope = (-1.5) / (3)
slope = -0.5
So, the rate of change is -0.5.
Therefore, the initial value is 1 and the rate of change is -0.5.
(-3,2.5) to (0,1) to (2,0)
Determine the initial value and the rate of change of the linear function given in the graph.
