Find the slope between two points, along with the line equation and distance between them.
Slope measures how steep a line is — it's the ratio of vertical change to horizontal change between two points, calculated as m = (y2 − y1) ÷ (x2 − x1). A slope of 2 means the line rises 2 units for every 1 unit it moves right; a negative slope means the line falls as it moves right.
Once you know the slope and one point on the line, you can find the y-intercept using b = y1 − m × x1, which gives you the complete equation in slope-intercept form: y = mx + b. This calculator also reports the straight-line distance between your two points using the distance formula, and the angle the line makes with the horizontal axis.
This tool works for any two points on a standard Cartesian (x, y) plane.
