yes

Step-by-step explanation:

because although some of the other are missing to be a function, it has to have an element of x and of y, it does not matter that some do not have it with one of y and one of x is enough

And if you are talking about relation it is also because they comply with the rules

Answers

Answer:

y = 1/2 x+4

Step-by-step explanation:

Slope intercept form is y = mx+b, where m equals the slope and b is the y-intercept.

The slope can be calculated using the formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex].

I'll be plugging in (2,5) and (4,6) to calculate the slope.

m = (6-5)/(4-2) = 1/2

The y-intercept is the y-coordinate of where the line meets the y-axis. In the graph, you can see that the line intersects with the y-axis at (0,4). The y-coordinate of (0,4) is 4, so therefore it is the y-intercept.

Plugin m = 1/2 and b = 4 into the slope-intercept formula (y = mx+b), and you get y = 1/2 x+4

It takes 3.5 cups of pancake mix and 2.625 cups of water to make 21 pancakes.

Step-by-step explain

First divide each by 6 to figure out how much mix and water it takes to make one pancake

1/6 mix + .125 cups water = 1 pancake

Multiple each by 21 to know how much mix and water it takes to make 21 pancakes

3.5 mix + 2.625 water = 21 pancakes

Answer:

Step-by-step explanation:

you multiply 3/4 times 21 then you will get 3/4 times 21/1 and the answer is 63/4 and simplify and get 15 and 3/4.
