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 for m)
(Substitute 2, for x, y)
(Multiply: )
Apply addition property of equality: If a = b than a + c = b + c.
(Add 1 to each side)
Apply commutative property of addition: a + b = b + a.
(Apply Additive inverse property: )
(Apply Additive identity property: )
(Add: )
Substitute for m and 2 for b in the Slope-intercept form equation.
The line equation in slope-intercept form is .
