B) The difference in the x-values for each interval is ___. This value is also constant because =-1/2(p+k)+10-(-1/2p+10)
=-1/2p-1/2k+10+1/2p-10
=-1/2intervals result in growth by equal differences.
Step 1: If the equal interval is k, the two endpoints of the interval will be labeled p and p + k. Label the endpoints of the corresponding interval on the y-axis of the graph below. Hint: First, substitute x=p into y=mx+b. Next, substitute x=p+k into y=mx+b
Step 2: Find the difference between the endpoints of the interval on the y-axis.
(1)
[y-value at x=p]-
(2)
[y-value at x=p+k]
