The graph is not decoration. It is the argument
Economics assignments reward students who can move between the model, the graph and the plain-English implication. Most lost points come from doing one of those three well and leaving the others implicit.

Say it in words, show it on a diagram, and connect them
A well-answered economics question usually states the mechanism in words, illustrates it on a correctly labeled diagram, and explains what the shift means for the firm or the market. Students who write a fluent paragraph without the diagram, or draw the diagram without explaining the shift, lose points on both routes.
Labeling is where diagram points actually go. Axes named with units, curves identified, the initial and final equilibria graded, and the direction of the shift shown. An unlabelled sketch earns very little regardless of whether the shape is right.
Then there is the applied half. Business economics usually asks what a firm should do given the analysis, which means the answer ends in a decision rather than in a diagram. Assignments that stop at the model have answered half the question.
- Mechanism explained in words before the diagram
- Diagrams labeled properly, including units and equilibria
- Elasticity used to justify pricing rather than just calculated
- An implication for the firm, stated explicitly
What we work on
Your own assignment and your own rubric
- Supply, demand and the difference between a shift and a movement
- Elasticity, and what it implies for pricing decisions
- Cost curves, and why the short run and long run differ
- Market structure from perfect competition through to monopoly
- Applied essays that end in a recommendation
We teach the method. You do the assignment
- We do not complete your problem sets or essays.
- We do not draw your diagrams for you to submit.
- We do not sit or assist during any exam or timed quiz.
- We do not supply completed work to adapt.
- We teach the reasoning on worked examples, then review your own work.

Frequently Asked Questions
A movement along the curve is caused by a change in price. A shift of the whole curve is caused by anything else: income, input costs, expectations, the price of substitutes. Confusing the two is the single most common diagram error and it usually makes the rest of the answer wrong.
Connect it to revenue. Where demand is inelastic, raising price raises revenue; where elastic, it lowers it. The assignment usually wants that link made explicitly, plus a note on what makes demand elastic for this particular product.
Usually yes, where the answer involves a market mechanism. Rubrics frequently award diagram points separately, and a labeled diagram often explains a shift more clearly than a paragraph can.
Often because the short run and long run are being mixed. In the short run at least one input is fixed, which is what produces diminishing returns. In the long run everything varies. Answers that use short-run logic on a long-run question look confused even when the arithmetic is fine.
Enough to ground the theory, cited. Applied economics assignments reward a real example that demonstrates the mechanism, and penalize unsupported assertions about what firms do.
