The online Slope Intercept Form Calculator is used to help you find the slope intercept form for the equation of the straight line which 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
