The linear function is .
Replace with y
The y-intercept is the value of y when x = 0.
\ (Substitute 0 for x)
(Apply Zero propduct property:
)
(Apply Additive identity property:
)
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)
According to addition property of equality: if a = b, then a + c = b + c.
\ (Add 1 to each side)
(Apply Additive identity property:
)
(Apply Additive identity property:
)
According to division property of equality: if , then
.
(Divide each side by 4)
(Cancel common terms)
The x-intercept is . The graph crosses the x-axis at (
, 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.
