Step 1

y < 5x - 4

As a first step let\'s plot the straight line y = 5x - 4

We need just two points to plot the line. Easiest way to get the two points is:

When x = 0, y = -4

When x = 1, y = 1

Hence, the two points are (0, -4) and (1, 1)

Please see the white board. The green line is the plot of y = 5x - 4

Step 2

Now test an arbitrary point say (0, 0)

y < 5x - 4 = 5 x 0 - 4 = -4

Hence, ...
