Question 147398: How do you graph 3x<2x-3 or 7x>4x-9

You can put this solution on YOUR website!
First isolate the variable of 3x%3C2x-3. Get x%3C-3. Then draw the graph of x=-3. Make sure to dot the line. Then shade everything to the left of the line. This shows that x can be anything up to -3, but not -3. Because that's where you draw the line.
Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
this equation defines a vertical line.

  • X intercept: -3. 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

It looks like this with the line dotted and a shaded area to the left of it.
