The expression is .

The equation is in slope-intercept form y = mx + c.

\

To graph the equation, first graph the .

According to subtraction property of equality: if , then .

              (Subtract 4x from each side) \ \

              (Commutative property: a + b = b + a)

                                (Additive inverse property: )

First find the y-intercept.

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

                               (Zero product property: )

                                     (Additive inverse property: )

Next find the x-intercept        

The co-ordinate point is (0, 4) \ \

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

\

According to addition property of equality: if a = b, then a + c = b + c.

              (Add 4x to each side) \

                               (Additive inverse property: )

                                     (Additive identity property: )

According to division property of equality: if , then .

                             (Divide each side by 4)

                                     (Cancel common terms)

The co-ordinate point is (1, 0) \ \

Use these ordered pairs to graph the equation.

1.     Draw a coordinate plane.

2.     Plot the points.

3.     Draw a line through these points.
