The equation is
.
Re write the equation Slope-intercept form line equation is 
(Subtract 2x from each side)
(Apply commutative property of addition:
)
(Apply additive inverse property:
)
(Apply additive identity property:
)
Slope of the equation
Next find the y-intercept.
\The y-intercept is the value of y, when x = 0.
\
(Substitute x = 0 in original equation)
(Multiply:
)
(Apply additive identity property:
)
The y-intercept is 4.
Slope of the equation
.
The y-intercept is 4.
