See how a steep slope of 3 makes the line rise quickly as x increases.
Frequently asked questions
- What does the slope mean?
- The slope m tells you how much y changes for every 1-unit increase in x. A slope of 2 means y goes up 2 for every 1 step to the right.
- What if the slope is zero?
- A slope of zero gives a horizontal line at y = b, with no x-intercept (unless b is also 0, in which case the whole x-axis is the line).
