Question

Which of the following equations represents the linear relationship shown in the table below?

X Y
2 7
3 9
4 11
5 13


A. y = 2x − 3
B. y = 2x + 3
C. y = 3x − 2
D. y = 3x + 2​

Answer 1

B

Explanation:

The equation is:

y = 2x + 3

Put x as 2.

y = 2(2) + 3

y = 4 + 3

y = 7

Put x as 3.

y = 2(3) + 3

y = 6 + 3

y = 9

Put x as 4.

y = 2(4) + 3

y = 8 + 3

y = 11

Put x as 5.

y = 2(5) + 3

y = 10 + 3

y = 13
