This is a bit confusing for me. I understand how the whole X axis and Y axis works, and various graphs, but for some reason the

questions asked on quizzes are confusing to me . . . anyway, here is the problem.
(?,-3) 4x+5y = -7

So I'm assuming I need to find the "X" Coordinate. . . . How???

Your coordinates are (x,y), here you just need to figure what 'x' is given that 'y' is equal to -3. So, just plug in -3 for 'y' in the equation and then solve for 'x', like so: 4x + 5(-3) = -7 ... then just use algebra to solve for what 'x' has to be. Hope this helps!

Consider the following dot plots.

The <u>correct answer</u> is:

A) The medians are both between 10 and 14 emails.

Explanation:

The <u>mode </u>is the easiest measure to find of a data set.
The <u>mode </u>of a data set is the data value that appears the most often.  In plot A, there are 3 dots at 10 and 3 dots at 15; this means the modes are 10 and 15.

In plot B, there are 3 dots at 5 and 3 dots at 15; this means the modes are 5 and 15.

They <u>do not have the same modes</u>.

The <u>median </u>of a data set is the middle value.  There are 10 dots in each dot plot; this means the medians will each be between two data points.

For plot A, we can see that the middle value is between 10 and 15.  
For plot B, we can see that the middle value is between 10 and 15.

This means that choice A is correct, the medians of both are between 10 and 14.

How do you graph the function g(x)
Verizon [17]
Lightly draw a vertical line at -3 (x= -3 is the divider) on the left side graph x + 1, on the right side graph 1/2x + 2. 
because these equations don't match up at the -3 coordinate, you have to draw an open (not colored in) circle at the beginning at the 1/2x-2 equation
