\"slope\"\"

\

Given points are \"\".

\

First, find the slope.

\

\"\"

\

Substitute \"\"1 for y2,  \"\"3 for y1, 2 for x2, and \"\"2 for x1  in slope formula.

\

\"\"

\

\"\"                     (Product of two same signs is positive)

\

\"\"                     (Add: \"\")

\

\"\"                              (Add: \"\")

\

\"\"                        (Simplify)

\

\"\"                              (Cancel common terms)\"\"

\

You know the slope and a point on the line, so use point - slope form \"\"

\

with either given point to write an equation of line.

\

Choose \"\".

\

\"\" (Substitute \"\"3 for y1, \"\"2 for x1 and \"\")

\

\"\"              (Product of two same signs is positive)

\

\"\"         (Apply distributive property: \"\")

\

\"\"               (Cancel common terms)

\

\"\"                 (Multiply: \"\")\"\"

\

Apply subtraction property of equality:If a = b then a \"\" c = b \"\" c.

\

\"\"      (Subtract 3 from each side)

\

\"\"            (Apply additive inverse property: \"\")

\

\"\"                 (Apply additive identity property: \"\")

\

\"\"                       (Subtract: \"\")\"\"

\

The equation of line is \"\" .
