Find the x-intercepts and y-intercepts of the equations and then graph them on the same coordinate plane.
Graph:
Similarities and Differences: See solution.
Equations | x=0 | y-intercept | y=0 | x-intercept |
---|---|---|---|---|
3x+y=6 | 3( 0)+y=6 | (0,6) | 3x+ 0=6 | (2,0) |
3x-y=6 | 3( 0)-y=6 | (0,-6) | 3x- 0=6 | (2,0) |
-3x+y=6 | -3( 0)+y=6 | (0,6) | -3x+ 0=6 | (-2,0) |
We are ready to go! Let's draw them on the same coordinate plane. This way we will be able to see the differences and similarities more clearly.
Now, let's interpret the graphs point by point.
