Question
Use the image to answer the question.
A coordinate plane ranges from negative 9 to 9 in unit increments on the x-axis and from 11 to negative 11 in unit increments on the y-axis. A line with arrows at both the ends joins three plotted points and extends beyond. The coordinates of the plotted points are: left parenthesis 0 comma 0 right parenthesis, left parenthesis 1 comma 1 right parenthesis, and left parenthesis 2 comma 2 right parenthesis.
Use the graph of y=x to determine an additional ordered pair (x, y) that satisfies the equation. Find the ordered pair (x, y) if the x-coordinate is 3.

The additional ordered pair (x, y) that satisfies the equation y=x when the x-coordinate is 3 can be found by simply substituting x=3 into the equation.
Therefore, the ordered pair (x, y) is (3, 3).
To find the ordered pair (x, y) if the x-coordinate is 3, we need to determine the corresponding y-coordinate on the graph of y=x.
Since the equation is y=x, the value of y is always equal to the value of x.
Therefore, when the x-coordinate is 3, the y-coordinate will also be 3.
Therefore, the ordered pair (x, y) with x=3 is (3, 3).
