What is the slope formula?

Back

The slope formula is given by m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on a line.

How do you find the slope between two points?

Back

To find the slope between two points, use the formula m = (y2 - y1) / (x2 - x1) and substitute the coordinates of the points.

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0, as there is no change in y regardless of the change in x.

Calculate the slope of the line given the points (3, 18) and (0, 18).

Back

The slope is 0, as both points have the same y-coordinate.
