What is the midpoint of EC ?

A: (t + p, r)

B: (p – t, r)

D: (p, r)

A: (t + p, r)

Step-by-step explanation:

To find the midpoint of EC

Let (x1, y1) = E(2t, 0) and  (x2, y2) = C(2p, 2r)

Midpoint = [(2t + 2p)/2 , (0 + 2r)/2]

= (2(t + p)/2 , 2r/2)

= (t + p, r)

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
