The line equation is .

First find the x-intercept, let y = 0.

                           (Replace y with 0)

              (Subtract 4 from each side)

                             (Simplify)

                        (Divide each side by 2)

                                (Simplify)

Since x = when y = 0 graph the ordered pair (, 0)

To find the y-intercept, let x = 0.

                        (Replace x with 0)

                                     (Simplify)

Since y = 4 when x = 0 graph the ordered pair (0, 4)

Use these ordered pairs to graph the equation.

\
• Draw a coordinate plane.
\
• Plot the points (, 0) and (0, 4)
\
• Draw a line through these points.
