A line graph, or line chart, shows info as a series of data points that are connected by line segments.
Answer:
B and D
Step-by-step explanation:
Then they all will equal the same thing when you divide them.
Example: A = 5 B = 20 20 divided by 5 = 4
C = 28 D = 7 28 divided by 7 = 4
Answer:
81
Step-by-step explanation:
Any number, wether it is negative or postive, will always be postive when there is a even exponent.
In this case, we have a -9, and a exponent thats 2.
Since 2 is a even number, -9^2 will be a postive value.
Now, what is the actual value of this?
Well, a exponent of 2 basiclly means 2 numbers being multiplied together.
Or in this case, 2 negative 9s being multiplied together.
THis will be:
-9*-9
=
As I said above, a even exponent makes a negative number postive.
You see here that a negative 9 is being multiplied by -9. When two negative numbers multiply together, they make a postive.
THis is why a even exponent makes a postive.
Hope this helps!
Answer:
See attachment
Step-by-step explanation:
The table that represent a direct variation is shown in the attachment.
To determine a direct variation from tables, you need to inspect the y-intercept of each table.
If there is a table with y-intercept of 0, then it represents a direct variation.
Or you could check the table with equation of the form: 
if you cannot see zero in the y-intercepts directly
