The linear function is
(Subtract 8 from each side)
(Apply Additive inverse property:
)
(Apply Additive identity property:
)
The y-intercept is the value of y when x = 0.
\ (Substitute 0 for x)
(Multiply:
)
(Apply Additive identity property:
)
(Divide each side by 3)
(Cancel common terms)
(Multiply each side by negative one)
(Product of two same signs is positive)
The y-intercept is . The graph crosses the y-axis at (0,
).
The x-intercept is the value of x when y = 0.
\ (Substitute 0 for y)
