\

Write an equation of a line in standard form by using two points as follow:

\

For example two points are $\"\"$ .

\

Substitute the values of $\"\"$ in the slope formula $\"\"$ .

\

$\"\"$ . $\"\"$

\

To find the y - intercept, substitute the values of $\"\"$ in the slope - intercept from of equation $\"\"$ and solve for b.

\

$\"\"$

\

$\"\"$ .

\

Substitute the values of $\"\"$ in the slope - intercept form of equation $\"\"$ . $\"\"$

\

The line equation is $\"\"$ .

\

Multiply each side by 5.
