Question

Which equation has a graph that includes the point (4.5, 14)? Select all that apply. A. y = 2x + 5 B. y = 3x + 1.5 C. y = 4x – 4 D. y = 5x – 8.5 E. y = 12x + 10

Answer 1

C

Explanation:

Answer 2

A and C

Explanation:

Just plug in the point into the equations:

a) 14 = 2(4.5) + 5

14 = 9 + 5 14 = 14 A is correct

b) 14 = 3(4.5) + 1.5

14 = 13.5 + 1.5 14 ≠ 15 B is not correct

c) 14 = 4(4.5) - 4

14 = 18 - 4 14 = 14 C is correct

d) is not correct 12 is already to large and 10 is not a negative so it is far to large
