This worksheet follows on from Shading Regions (A) and now looks at more complicated straight-line equations in the form y=mx+c and ax+by=c.

In the lefthand table, learners must define the inequality for the unshaded region and state whether a point is inside, outside the region or on the lines.

The righthand side table asks learners to draw the lines and indicate the region and then decide if a given point is inside, outside the region or on the lines.
