Given the System of Equations:
You can graph the lines by finding the x-intercept and the y-intercept of each:
1. Find the x-intercept of each line by substituting this value of "y" into each equation and solving for "x":
Because, by definition, the value of "y" is zero when the line intersects the x-axis.
Then:
- For the first line:
- For the second line:
2. Find the y-intercept of each line by substituting this value of "x" into each equation and solving for "y":
Because, by definition, the value of "x" is zero when the line intersects the y-axis.
Then:
- For the first line:
- For the second line:
Therefore, you know that the first line passes through these points:
And the second line passes through these points:
Knowing these points, you can graph both lines:
Notice that both lines intersect each other at a point. That point is the solution of the System of Equations.
Hence, the answer is:
