Graph the following inequality. Click on the graph until the correct one appears.
exis [7]

Answer:     Its the first one

You draw the graph of the line y=3x+5

but make the line dotted.

Label the line y>3x+5

Note that if instead we hade y≥3x+5 the line would be solid.

If you draw a line parallel to the y-axis through any x-value the value of y can be any on that vertical line that is above but not on the line y=3x+5

. So you end up with a 'feasible' region of solutions for y
