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 0.5 for m)
(Substitute 6, 4 for x, y)
(Multiply: )
Apply subtraction property of equality: If a = b than a c = b c.
(Subtract 3 from each side)
Apply commutative property of addition: .
(Apply Additive inverse property: )
(Apply Additive identity property: )
(Subtract: )
Substitute 0.5 for m and 1 for b in the slope-intercept form equation.
The line equation in slope-intercept form is .
