A linear function contains the following points. X - 4 | 4 0 5 What are the slope and y-intercept of this function? A. The slope is 4. The y-intercept is (5.

B. The slope is The y-intercept is (0,5).

C. The slope is - 1 Tthe y-intercept is (0,5).

D. The slope is -4. The y-intercept is (0,5).

The answer is B.

Step-by-step explanation:

when x is 0, y is 5. So that is the yintercept and 4-5=-1 -4-0=-4 do 1/4

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
