I am not familiar with LaTeX, but to create a scatterplot, you just plug to co-ordinates onto the plane without connecting the dots. 

For example, one point is 275, 76 another one is 310, 77

Make sure the x and y correspond to each other.

Hope this helped,

Find the slope of the line containing the points P1 and P2:  

P1(6, -4)     P2(4, -2)

To find the slope, it is the difference in y value and different in x value

-4 - ( -2) divided by 6 - 4

This is -2 over 2

which also is -1

I hope this helped,

Is (1, -3) a solution of y = -2x – 1 (show your work AND give me a yes or no answer)?

Yes, if you plug in 1 for x and -3 for y, the expression is true.

-3 = -2 * 1 - 1

Is true

I hope this helped! :)

Thanks!

Thanks Melody!

The problem with math puns is that calculus jokes are all derivative, trigonometry jokes are too graphic, algebra jokes are usually formulaic, and arithmetic jokes are pretty basic. But I guess the occasional statistics joke is an outlier.

Here’s some advice: At a job 
interview, tell them you’re willing to give 110 percent. Unless the job is a statistician.

I don't get any of the jokes... 

Am I not smart enough?

(a) 

92 - 9 / 92 which is about 0.9

Answer is a 90 percent change

(b)

absolute value of 24 - 96 / 24 which is 0.3

Thhe answer is a 30 percent change

(c) 

75 - 74 / 75 which is 0.013333....

Answer is a 1 percent change
