Answer:

Step-by-step explanation:

the general formula is

(y-y1)=m(x-x1) where

m is the slope

(x1, y1) are the coordinate of one point that belongs to the line

(x,y) are just variables

If you are given point (-3,4) and slope 2 for example the equation is

m=2, (x1, y1)=(x1=-3, y1=4)

so the equation is

(y-4) = 2(x-(-3)) so is

(y-4) =2(x+3)
