\

First find the slope of the line.

\

$\"\"$

\

$\"\"$ (Substitute $\"\"$ for x₁, 1 for y₁, $\"\"$ for x₂ and $\"\"$ for y₂)

\

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

\

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

\

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

\

$\"\"$ (Multiply $\"\"$ , by reciprocal of 4)

\

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

\

Next find the y-intercept value by replacing m with $\"\"$ , y with 1 and x with $\"\"$ in the equation $\"\"$ .

\

\

$\"\"$ (Cancel common terms)

\

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

\

$\"\"$ (Subtract $\"\"$ from each side)

\

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

\

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

\

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

\

Replace m with $\"\"$ and b with $\"\"$ in the slope-intercept form line equation $\"\"$ .

\

\

$\"\"$ (Simplify) $\"\"$

\

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