Please look in your text book for this problem Statement  The equation is .

First find the y-intercept.

The y-intercept is the value of y, when x = 0. (Substitute x = 0 in original equation) (Zero product property: ) (Multiply each side by negative one) (Product of two same signs is positive)

The y-intercept is .

The co-ordinate point is  Next find the x-intercept.

The x-intercept is the value of x, when y = 0. (Substitute y = 0 in original equation) (Divide each side by 5) (Cancel common terms) (Divide: )

The x-intercept is 7

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.  The x-intercept is 7 and y-intercept is . TESTIMONIALS
