The line equation in slope-intercept form is , where m is
the slope and b is the y-intercept.
Find the y-intercept value by replacing m with 2, y with –2 and x with 4 in
the equation .
(Multiply: )
(Subtract 8 from each side)
(Apply commutative property of addition: )
(Apply additive inverse property: )
(Subtract: )
Replace m with 2 and b with –10 in the equation .
(Simplify)
The slope-intercept form of the line equation is .
