Question

A linear function contains the following points. x 0 2 4 6 y 3 -1 -5 -9
What are the slope and y-intercept of this function?

A. The slope is -2. The y-intercept is (3,0).
B. The slope is -1/2 The y-intercept is (0,3)
C. The slope is 2. The y-intercept is (0,3)
D. The slope is -2. The y-intercept is (0,3)

Answer 1

Answer:

D. The slope is -2. The y-intercept is (0,3)

Step-by-step explanation:

You can use any two points.

Let's use the first two points: (0, 3), (2, -1)

slope = (y_2 - y_1)/(x_2 - x_1)

slope = (-1 - 3)/(2 - 0)

slope = -4/2

slope = -2

The y-intercept occurs when x = 0. For x = 0, y = 3, so the y-intercept is 3 which means the point (0, 3).

Answer: D. The slope is -2. The y-intercept is (0,3)

Answer 2

The answer is d -2 the y-Intercept
