I am a secondary algebra I student
How do I find x and y and graph this problem.
3x + y < 5

Hi Lori
First add 3x to both sides to rewrite your inequality as y < 5  3x. Now consider the equation y = 5  3x an plot its graph.


Choose an xvalue, for example x = 1. The point satisfying y = 5  3x with x = 1 is (1,2). The points satisfying y < 5  3x with x = 1 are the points with x = 1 and y value less than 2, that is the points in the diagram to the right coloured orange.


Do the same for every xvalue to see that the graph of y < 5  3x is the halfplane coloured orange in the diagram to the right.
