\"slope-intercept\"\"

\

Observe the figure, first find the y-intercept value by replacing m with \"\"1, y with \"\"1 and x with 4 in the equation \"\".

\

\"\"

\

\"\"                         (Product of two different signs is negative)

\

Apply additon property of equality: If a = b then a + c = b + c. \ \

\

\"\"            (Add 4 to each side)

\

\"\"                (Apply commutative property of addition: \"\")

\

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

\

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

\

Replace m with \"\"1 and b with 3 in the equation \"\".

The slope-intercept form line equation is \"\".
