The Slope Intercept Form Calculator is used to help you find the slope intercept form for the equation of the straight line that passes through two points. It also calculates the slope and the y-intercept of the line.
The slope intercept form for the equation of any straight line is given by:
y = mx + b
m is the slope of the line
b is the y-intercept of the line
The slope m of the line through any two points (x1, y1) and (x2, y2) is given by:
The y-intercept b of the line is the value of y at the point where the line crosses the y axis. Since for point (x1, y1) we have y1 = mx1 + b, the y-intercept b can be calculated by:
b = y1 - mx1
To calculate Slope Intercept Form you need input two points (x1, y1) and (x2, y2). The tool will calculate the slope and the y-intercept of the line based on the formula above. The calculator will show you the chart based on your input as well. You can also download the result in PDF filetype.
