Slope Intercept Form y = mx + b
This is a video on how to find the slope intercept form equation of a line.
On this video two points are given with their corresponding coordinates to get the slope intercept form equation.
Using these coordinates, the general slope intercept form equation y = mx + b will then be derived.
Any straight line can use the equation y = mx + b.
Using only the coordinates of two points, first we need to solve for the slope using the equation m = (y2 – y1) / (x2 - x1).
Using only the coordinates of two points, first we need to solve for the slope using the equation m = (y2 – y1) / (x2 - x1).
After finding the slope, then intercept or b will then be solved. Use the equation y = mx + b, where the value of y and x can be taken from any of the coordinates of the two points.
When the slope and b have been found substitute them to the slope intercept form equation.
