\

The line equation in slope-intercept form is $\"\"$ , where m is the slope and b is the y-intercept.

\

First find the slope (m).

\

The slope formula is $\"\"$ .

\

$\"\"$ (Replace $\"\"$ with 2, $\"\"$ 4, $\"\"$ 3 and $\"\"$ 1)

\

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

\

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

\

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

\

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

\

Next find the y-intercept (b).

\

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

\

$\"\"$ (Substitute 2, $\"\"$ 4 for x and y)

\

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

\

Apply addition property of equality: If a = b than a + c = b + c.

\

$\"\"$ (Add $\"\"$ to each side)

\

Apply commutative property of addition: $\"\"$ .

\

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

\

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

\

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

\

Substitute $\"\"$ for m and $\"\"$ for b in the Slope-intercept form equation.

\

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

\

Option B is correct.
