Slope from a Graph

Front

What is the definition of slope?

Back

Slope is a measure of the steepness or incline of a line, typically represented as the ratio of the vertical change to the horizontal change between two points on the line.

What is the formula to calculate slope between two points (x1, y1) and (x2, y2)?

Back

The formula for slope (m) is given by: m = (y2 - y1) / (x2 - x1).

How do you identify the slope from a graph?

Back

To identify the slope from a graph, select two points on the line, determine the vertical change (rise) and the horizontal change (run), and use the formula m = rise/run.

Calculate the slope between the points (1, 2) and (4, 5).

Back

The slope is m = (5 - 2) / (4 - 1) = 3 / 3 = 1.

Calculate the slope between the points (-1, 3) and (2, 6).

Back

The slope is m = (6 - 3) / (2 - (-1)) = 3 / 3 = 1.
