Graph solution of inequalities of coordinate plane

An inequality on a coordinate plane consist of a boundary line and a area in which each point is the possible solution.

If the inequality has a sign , then the line will be a solid line and its point are included in the solution.

If the inequality has a sign '>' , '<' then the line will be a dotted line and its point are not included in the solution.

Given the inequality:  

Subtract 5x from both sides we get;

Multiply both sides by -1 we get;

Graph:

Plot the boundary line y = 5x -3 (as a dotted because  not included equal to) and

the shaded area below as  as shown below in the graph.

2,600 divided by 80 = 32.5
