Step-by-step explanation:
To find the solution set, substitute and evaluate each point into the given equation. If it makes it true then it is part of the solution set.
14. y = 4x + 1
(2,-1)
-1 = 4*2 + 1
-1 = 9 FALSE
(1,5)
5 = 4*-1 + 1
5 = -3 FALSE
(9,2)
2 = 4*9+1
2 = 37 FALSE
(0,1)

If 7 x 88 = 616, then 616 / 88 = 7.
7 / 616 = 0.011
88 / 616 = 0.14
88 / 7 = 12.57
616 / 88 = 7
Hope this Helps!!
