The answer is 854 for sure. I did the test and got it all right.
Answer:
Quadrant 2, x-axis
Step-by-step explanation:
Point C is on top left side of the x-y graph, which is quadrant 2.
An axis refers to line, so the x axis the is horizonal line, as it says on the right end of it. The y axis is the vertical line, noted at the top of the line.
The only line that's on a line is point D and it's on the x-axis.
Answer: 
Step-by-step explanation:
1. Substitute
into first equation and solve for "x" in order to find the x-intercept of the first line:

2. Substitute
into the first equation and solve for "y" in order to find the y-intercept of the first line:

Knowing that first line passes through the points
and
, you can graph it.
3. Substitute
into second equation and solve for "x" in order to find the x-intercept:

4. Substitute
into the second equation and solve for "y" in order to find the y-intercept of the second line:

Knowing that second line passes through the points
and
, you can graph it.
The solution of the system of equations is the point of intersection between the lines. Therefore, the solution of this system is:
