\

First find the slope (m).

\

Slope formula is $\"\"$ .

\

Substitute the coordinates of points into the slope formula.

\

$\"\"$ (Replace $\"\"$ with 3, 7, $\"\"$ 2 and $\"\"$ 3)

\

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

\

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

\

The slope of $\"\"$ . $\"\"$

\

Next find the y-intercept (b).

\

The equation in slope-intercept form is $\"\"$ ,

\

Where m is slope, b is the y-intercept.

\

$\"\"$ (Substitute 2 for m)

\

$\"\"$ (Substitute 3, 7 for x, y)

\

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

\

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

\

$\"\"$ (Subtract 6 from each side)

\

Apply commutative property of addition: a + b = b + a.

\

$\"\"$

\

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

\

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

\

Substitute 2 for m and 1 for b in the Slope-intercept form equation.

\

$\"\"$

\

$\"\"$

\

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