From x=a to x=b, with n subintervls, the width between each is (b-a)/n
so from x=3 to x=5 and 4 intervales is (5-3)/4=2/4=1/2
increments of 1/2 each time
we need 4 of them
I see that xi is the right endpoint so I would guess that we take the right <span>Riemann sum
so we start at 3+0.5 or 3.5
so 3.5, 4,4.5,5
C I would say

Answer:
C
Step-by-step explanation:
y=mx+b
3 = -2(3) + b
3 = -6 + b
9 = b
y = -2x + 9
2x + y = 9
4/10, 6/15, 8/20, 10/50, and 12/60.
