Final: Draw the Fence

Part of the Graphs & Systems section of Coddy's Algebra journey. Lesson 60 of 61.

Rearrange the inequality to isolate y. Identify the boundary line, decide whether it is solid or dashed, and choose which side to shade.

Challenge

Hard

Shade the solutions of $3x-y > 2$ .

Try it yourself

3x-y > 2

Shade the region
