Question

Reward = Medal

Which equation is represented by the table?

x y (x, y)
0 3 (0, 3)
1 5 (1, 5)
2 7 (2, 7)

options:


A.
y = 2x + 3

B.
y = x + 3

C.
y = 3x + 2

D.
y = 5x

Answer 1

You can exclude C and D, because they don't have y-intercept of (0,3)
(rather they have y-intercepts (0,2) and (0,0) respectively. )

You see that each time the x value goes up by 2, so the slope is 2. Hence the answer is ?
