Answer:

y = 2.3x is a linear function.

Step-by-step explanation:

A linear function is a function with all of its terms to the first degree, in other words, none of its terms has an exponent. This means that when the function is plotted out, the resulting graph will be a line. The function, ( y = 2.3x) satisfies both of these requirements, hence it is linear.

Find the missing value of the direct variation (2,5) (5,y)
Karolina [17]

Answer:

The missing value y=12.5 and we have (5,12.5)

Step-by-step explanation:

The formula used for direct variation is:

y\: \alpha \:x\\y=kx

We need to find missing value (2,5)(5,y)

First we will find k, and then y

We have x=2, y=5

Find k:

y=kx\\5=k(2)\\k=\frac{5}{2}\\k=2.5

Now, we cam find missing value in (5,y)

We have x=5, k=2.5 and y=?

y=kx\\y=2.5(5)\\y=12.5

So, the missing value y=12.5 and we have (5,12.5)
