With a slope of 4

A point (x

Calculate the point-slope form.

The standard line equation is

y = mx + b

Rearrange that equation to solve for b

we get b = y - mx.

b = 2 - 12

b = -10

Setting x = 0 in y = 4x - 10

y = 4(0) - 10

y =

y - 2 = 4(x - 3)

y = 4x - 10

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

- m = (y
_{2}- y_{1}) / (x_{2}- x_{1}) - y = mx + b
- Distance = Square Root((x
_{2}- x_{1})^{2}+ (y_{2}- y_{1})^{2}) - Parametric equations are written in the form (x,y) = (x
_{0},y_{0}) + t(b,-a) - Midpoint = ((x
_{2}+ x_{1})/2, (y_{2}+ y_{1})/2)
