What is the formula for finding the slope of a line given two points?

Back

The slope (m) of a line through two points (x1, y1) and (x2, y2) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Calculate the slope of the line that includes the points (6, -1) and (-4, 3).

Back

Using the slope formula: m = (3 - (-1)) / (-4 - 6) = 4 / -10 = -2/5.

What is the coordinate plane?

Back

The coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Each point on the plane is defined by an ordered pair (x, y).
