Step-by-step explanation:
Hello!
Find the slope using the slope formula:
m = (y2 - y1) / (x2 - x1)
Plug in the points (-2, 8) and (0, 6) to solve:
m = (6 - 8) / (0 - (-2))
m = -2 / 2
m = -1
The y-intercept of the function is the y-value when x = 0.
According to the table, at x = 0, y = 6. Therefore, the y-intercept is (0, 6).
The correct answer is B.
