Answer:

The table represents a linear function because the rate of change is constant or all the points lie on a straight line.

Step-by-step explanation:

From the given table it is noticed that the line passing through the points (2,5), (4,10), (6,15) and (8,20).

The slope of the line is

m=\frac{y_2-y_1}{x_2-x_1}=\frac{10-5}{4-2}=\frac{5}{2}

The slope of line is \frac{5}{2}. It means the value of y increased by 5 if the value of x increased by 2.

From the given points we can noticed that the value of y increased by 5 if the value of x increased by 2. So, the function has same slope for any two points.

Since the rate of change (slope) is same for all points, therefore the table represents a linear function.

If we plot these points on a coordinate plane and connect then we get a straight line. I means it is a  linear function.

It is linear, because when you graph all the points they are in a straight line. And because you can draw a line straight threw the middle of the points.

Hayden has 6 rolls of dimes there are 50 dimes in each roll. How many dimes does he have altogether
DerKrebs [107]
This is pretty simple. :) Since you have 6 rolls of dimes with 50 dimes in each, you would just do 6*50 which equals 300. So Hayden has 300 dimes altogether. Hope this helps! :)
