Writing Inequalities from Graphs (B) WORKSHEET

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