\"slope\"\"

\

Given points are \"\"

\

Next, 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: \"\")\"\"

\

\"\"       (Subtract 3 from each side)

\

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

\

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

\

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

\

The equation of line is \"\" .
