Direct Line Conversion

1. How does this conversion work?

---

1. First get the line equation from the points#^a29a1d
2. see if ==m≤1==
   1. for every point of ==x(x is increased by 1 in every step) calculate y==
3. else
   1. for every point of ==y(y is increased by 1) calculate x==

2. How to get equation from the points? ^a29a1d

1. First calculate slope m, using the equation

$$ m = (y_2-y_1)/(x_2-x_

2. Then get b by plug in x_1 and y_1 in the line equation.
