3x+2<115

Change it to an equation
3x+2=115

Subtract 2 from each side
3x=113

Divide by 3
x=113/3

Make it an inequality again
x<113/3

Graph it
Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
this equation defines a vertical line.

  • X intercept: 37.6666666666667. 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


Shade to the left of the graph.
