The equation is

The equation is in slope-intercept form.

To graph the equation, first graph the .

(Subtract *x* from each side)

(Commutative property: )

(Additive inverse property: )

(Additive identity property: )

(Divide each side by 3)

(Cancel common terms)

(Multiply each side by negative one)

(Product of two same signs is positive)

First find the *y*-intercept.

The *y*-intercept is the value of y, when .

(Substitute )

(Additive identity property: )

(Divide: )

Next find the *x*-intercept

The co-ordinate point is

The *x*-intercept is the value of *x*, when .

(Substitute )

(Multiply each side by 3)

(Cancel common terms)

(Zero product property: )

(Add 9 to each side)

(Commutative property: )

(Additive inverse property: )

(Additive identity property: )

The co-ordinate point is
