The expression is .
The equation is in slope-intercept form.
\To graph the equation, first graph the .
(Divide each side by 3)
(Cancel common terms)
(Divide:
)
(Subtract x from each side)
(Apply commutative property of addition: a + b = b + a)
(Additive inverse property:
)
(Divide each side by negative one)
(Cancel common terms)
First find the y-intercept.
\The y-intercept is the value of y, when x = 0.
\ (Additive identity property:
)
(Divide:
)
Next find the x-intercept
\The co-ordinate point is
The x-intercept is the value of x, when y = 0.
\ (Multiply each side by negative one)
(Cancel common terms)
(Zero product property:
)
(Add x to each side)
(Additive inverse property:
)
(Additive identity property:
)
Next find the y-intercept.
\The co-ordinate point is (3, 0)
