 PAGE: 77 SET: Exercises PROBLEM: 1  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  Use these ordered pairs to graph the equation.

1.     Draw a coordinate plane.

2.     Plot the points.

3.     Draw a line through these points.  TESTIMONIALS
 "I want to tell you that our students did well on the math exam and showed a marked improvement that, in my estimation, reflected the professional development the faculty received from you. THANK YOU!!!" June Barnett "Your site is amazing! It helped me get through Algebra." Charles "My daughter uses it to supplement her Algebra 1 school work. She finds it very helpful." Dan Pease
