Which equation does not represent a line with an x-intercept of 3?
A) y = -2x + 6
B) y = -1/3 + 1
C) y = 2/3x - 2
D) y = 3x - 1

Respuesta :

Answer: D. y=3x-1 does not =3

Step-by-step explanation:

To find the x-intercept, we let y=0 and solve for x. 

Using choice A: 

0=-2x+6 

2x=6 

x=3 

Using choice B: 

0=− 1/3x + 1

1/3x = 1

x = 3

Using choice C: 

0= 2/3x−2 

−2/3x = -2

x=3 

Using choice D: 

0=3x-1 

-3x=1 

x=−1/3

So, the correct answer is choice D. Does NOT = 3
