A graphing calculator can be helpful for these.
A) Since neither inequality includes the "or equal to" case, the boundary line for the solution set is a dashed line. For the first inequality, the shading is above the line; for the second, the shading is below the line. The solution set is points to the right of perpendicular lines with slope -2 and +1/2 through point (2, -1).
B) The point -2, 3 satisfies, neither inequality.
.. 3 > -2(-2) +3 . . . FALSE
.. 3 < 1/2(-2) -2 . . .FALSE

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.
