The linear function is .
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 5. The graph crosses the y - axis at (0, -2).
The x-intercept is the value of x when y = 0.
\ (Substitute 0 for y)
(Add 2 to each side)
(Apply Additive identity property: 2 + 0 = 2)
(Apply Additive inverse property:
)
According to division property of equality: if , then
.
(Divide each side by 4)
(Cancel common terms)
(Divide:
)
The x - intercept is 3. The graph crosses the x - axis at .
