\

First find the slope of the line.

\

$\"\"$

\

$\"\"$ (Substitute 1 for x₁, 1 for y₁, 7 for x₂ and 4 for y₂)

\

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

\

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

\

$\"\"$ (Divide: $\"\"$ ) \ \ $\"\"$

\

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

\

in the equation $\"\"$ .

\

\

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

\

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