Demand Curve: Demand curves are always downward sloping. 'Demand' and 'Downward' both start with a 'D'. So, you can remember the slope of the demand curve by remembering that the curve that starts with 'D' slopes downward.

Supply Curve: Supply curves are usually upward sloping. The word "Supply" has "UP" in it. So, if the name of the curve has an 'UP' in it, it slopes up.

Equilibrium Graph: The word price has a vertical line in the letter 'P,' so price is always on the vertical axis/y-axis. Since price is on the y-axis, quantity (the other variable in equilibrium graphs) is on the horizontal axis.

Elasticities of Demand and Supply:

Perfectly Inelastic: Inelastic begins with an 'I', so the perfectly inelastic curve looks like an 'I'. In other words, it's vertical.

Perfectly Elastic: Elastic starts with an 'E', and there are 3 horizontal lines in the letter E, so a perfectly elastic curve looks like an 'E'/is horizontal.
