How do you find the equation of two endpoints?

Answer 1

the equation of a line is given in the form ax+by+c

c is the y intercept...in other words...when x=0 what is y?

b is how many y's (just to round a to an integer usually)

but a is the gradient.

a can be found with a simple equation.

the two coordinates you have....(x,y) and (x2,y2)

(Y2-Y) divided by (X2-X)

using this u can substitute your A value in....and one of your coordinates (the x and y) and figure out what c is :)
