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

First find the y-intercept value.

$\"\"$ (Substitute 3 for m)

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

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

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

$\"\"$ (Add 6 to each side)

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

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

Substitute 3 for m and 10 for b in the Slope-intercept form equation.

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