Answer
Refer to the step-by-step part below for the solution.
$(1, -1)$ is also a solution of $2x-y=3$
Work Step by Step
An ordered pair is a solution of an equation if its x and y coordinates satisfy the equation.
Substitute the x and y values of each ordered pair into the equation to check if they satisfy the equation.
For $(0, -3)$:
$2x-y=3
\\2(0)-(-3)=3
\\0+3=3
\\3=3$
Thus, $(0, -3)$ is a solution of the equation.
For $(2, 1)$
$2x-y=3
\\2(2)-1=3
\\3=3$
Thus, $(2, 1)$ is a solution of the equation.
Plot the two points and connect them using a line. (Refer to the image below for the graph.)
Note that the point $(1, -1)$ is also on the line.
Thus, $(1, -1)$ is also a solution of the equation $2x-y=3$
