Question

What is the equation represented by the table above?

A y = 8x
B y = x + 7
C y = 5x + 3
Dy = 3x + 5

Answer 1

Answer is D

Explanation:

A. 14=8(3), 14≠24

B. 14=3+7 , 14≠10

C. 14=5(3)+3, 14≠18

D.14=3(3)+5, 14=9+5 14=14

Answer 2

C: y = 5x + 3

Explanation:

Note that if x changes from 1 to 3 (the "run"), y changes from 8 to 14 (the "rise"). Thus the slope of the line represented by the table is m = rise/run = 6/2, or m = 3. Answer choice D is the only one that displays a slope of 3.
