Since its telling you that x is the number of years and the question is "How much does the cost of milk increase EVERY YEAR" then you can conclude that the cost is increasing by 0.25 each year

Answer:

Option B is correct

$0.25 does the cost of milk increase every year

Step-by-step explanation:

Slope-intercept form is given by:

y = mx+b       .....[1]

where, m is the rate and b is the initial value

Given the function:

y = 0.25x+3.5

where,

y represents the cost of a gallon of milk.

and

x represents the number of years.

We have to find how much does the cost of milk increase every year.

On comparing given function with [1] we have;

m = 0.25 and b = 3.5

Initially cost of milk = $3.5

and

cost of milk increase every year = $0.25

Therefore, $0.25 does the cost of milk increase every year

Points (−3, 5) and (3, 5) on the coordinate grid below show the positions of two players on a tennis court:
Anna35 [415]

Answer:

4.  Player 2's position is Player 1's position reflected across the y-axis; only the signs of the x-coordinates of Player 1 and Player 2 are different.

Step-by-step explanation:

Player 1's position is (-3, 5).

It means that it is 3 units left from the origin and 5 units above the origin.

Player 2's position is (3, 5).

It means that it is 3 units right from the origin and 5 units above the origin.

Hence, the two points are on the same horizontal line bisected by the y-axis.

So, Player 2's position is Player 1's position reflected across the y-axis; only the signs of the x-coordinates of Player 1 and Player 2 are different.
