Point-slope intercept — 7-topic bundle

Linear equations are equations where the highest power of the variable (like x or y) is 1. When you graph them, they always make a straight line.

Slope-intercept form is written as:

y = mx + b

Let's break down each part:

When we talk about lines on a coordinate plane, their slope tells us two key things: how steep they are and in what direction they're going. The beauty of parallel and perpendicular lines is that their slopes have very specific, predictable relationships.
