The linear equation is .

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

(Substitute 0 for x)

The y-intercept is 1. The graph crosses the y-axis at (0, 1).

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

(Substitute 0 for y)

Apply addition property of equality: if a = b then a + c = b + c.

(Apply additive identity property: a + 0 = a)

The x-intercept is 1. The graph crosses the x-axis at (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.

Graph of the linear equation is
