THE LEARNING SHELF

Start where you are.

A short guide for the step that is not quite clicking yet.

Start here

The slope formula

Understand why change in y is divided by change in x.

Think visually

Rise over run

Follow horizontal and vertical changes without mixing their order.

Connect the steps

Slope-intercept form

Use a slope and a point to find the intercept and line equation.

Another viewpoint

Point-slope form

Start with a known point before rearranging into y = mx + b.

Untangle a common mix-up

Zero or undefined?

Horizontal, vertical and repeated-point cases explained side by side.

Read the graph

Positive & negative slope

Separate a line’s direction from how sharply it changes.

Go one step further

Parallel & perpendicular

Use equal slopes and negative reciprocals, including the exceptions.

Reading helps. Trying makes it stick.

Put the method to work with five questions.
