Those are linear equations.
The graph of a linear equation is a straight line.
To draw each line you just need two points.
To find a point, you just pick a value for the x or the y , and solve for the other variable.
Choose values that make the calculations and the graphing easy.
Zero is often a good choice.
Finding points to graph x%2By=-3
When x=0 , 0%2By=-3 --> highlight%28y=-3%29 .
That gives you point (0,-3).
When y=0 , x%2B0=-3 --> highlight%28x=-3%29 .
That gives you point (-3,0).
Finding points to graph x%2By=7
When x=0 , 0%2By=7 --> highlight%28y=7%29 .
That gives you point (0,7).
When y=0 , x%2B0=7 --> highlight%28x=7%29 .
That gives you point (7,0).
The graph (with the points circled, looks like this:
The line for x%2By=-3 is drawn in blue.
The lines are parallel.
As a system of linear equations,
system+%28x%2By=-3%2Cx%2By=7%29 has no solution.
That should be obvious from the start, because if x%2By is -3 ,
it cannot be 7 at the same time (for the same x and y )
