Slope intercept form is a function of a straight line with the form y = mx + b where m is the slope of the line and b is the y-intercept. Slope refers to how steep the line changes as the values of x change where the y-intercept is where the […]

## Slope Intercept Form – Equation of a Line Example

What is slope? Simply put, slope refers to the steepness of a line. The larger the slope, the steeper the line. Slope is often referred to as ‘rise over run’ because it is calculated by the change in the vertical (rise) divided by the change in the horizontal (run). When […]
