Slope (m) = OR angle of incline (?) = ° Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m.

In the equation y = mx + b for a straight line, the number m is called the slope of the line. Let x = 0, then y = m ? 0 + b, so y = b. The number b is the coordinate on the y-axis where the graph crosses the y-axis.

The equation of a line of best fit can be represented as y=mx+b y = m x + b , where m is the slope and b is the y-intercept. We will take a look at two examples show a scatter plot with a line of best fit to understand the concept of how to approximate the equation of a line of best fit and make predictions.
