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)

                                   (Apply Additive identity property: 0 + 3 = 3)

The y-intercept is 3, so the graph intersects the y-axis at (0, 3).

Find the x-intercept.

The x-intercept is the value of x, when y = 0.

                             (Substitute y = 0 in original equation)

Apply subtraction property of equality: If a = b then a – c = b – c.

                 (Subtract 3 from each side)

                               (Simplify)

The x-intercept is , so the graph intersects the x-axis at (, 0).

Graph Using Intercepts:

Use these ordered pairs to graph the equation.

1.     Draw a coordinate plane.

2.     Plot the points.

3.     Draw a line through these points.
