You can put this solution on YOUR website!
Graph y=-3. Then graph x=6. Your graphs should look like this:
y=-3
Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
This equation defines a horizontal line. There is no X intercept. Y intercept is -3%2F1=-3

x=6
Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
this equation defines a vertical line.

  • X intercept: 6. X intercept is the intersection of the line with the x axis.

  • Y intercept: not defined (the line IS vertical)

  • Slope: not defined, can be thought of as infinite

graph%28+500%2C+500%2C+6-5%2C+6%2B5%2C+-10%2C+10%2C+1000000x-1000000%2A6+%29+


Then to get y%3E=-3, Shade above the line you just graphed. You are done there.
Then to get x%3E=6, shade to the right of the line you just graphed. You are done there.
