Answer:

Step-by-step explanation:
The
-intercept of a line is the
value when
. In the equation
, we can solve for its equation when we plug in
.
Solving for
when
:
.
So the
-intercept of the equation
is
.
To find what equation has the same
-intercept, we can do the same process for each equations given by the choices. However, I can see that the equation,
, has the
-intercept. If in doubt, you can check for the solution below or solve each equations for yourself.
Solving for
when
:

I don’t really know what this means
