 # Line Equation-Slope-Distance-Midpoint-Y intercept Calculator

## Enter 2 points 1 point and the slope

Point 1:
(x1 = , y1 = )   Slope: Point 2:
(x2 = , y2 = )    b:

### How does the Line Equation-Slope-Distance-Midpoint-Y intercept Calculator work?

Enter 2 points, and this calculates the following:
* Slope of the line (rise over run) and the line equation y = mx + b that joins the 2 points
* Midpoint of the two points
* Distance between the 2 points
* 2 remaining angles of the rignt triangle formed by the 2 points
* y intercept of the line equation
* Point-Slope Form
* Parametric Equations and Symmetric Equations

Or, if you are given a point on a line and the slope of the line including that point, this calculates the equation of that line and the y intercept of that line equation, and point-slope form.

Also allows for the entry of m and b to form the line equation
This calculator has 7 inputs.

### What 6 formulas are used for the Line Equation-Slope-Distance-Midpoint-Y intercept Calculator?

1. m = (y2 - y1) / (x2 - x1)
2. y = mx + b
3. Distance = Square Root((x2 - x1)2 + (y2 - y1)2)
4. Parametric equations are written in the form (x,y) = (x0,y0) + t(b,-a)
5. Midpoint = ((x2 + x1)/2, (y2 + y1)/2)
