I'm dancing right now in my chair taking an online test. Thank you for the help

[wunertragick]

Thank you for this video! My professor read from a power point slide and didn't break it down the way you did. I learned more through this video then from a week's worth of class.

Wow, is there anything more boring than someone reading from a power point? Thanks for watching.

Sir what if we are given years on the y axis

[nicholasheber]

I really appreciate you taking the time to explain this! I was curious, is there a reason the actual's are treated as all being positive numbers even though most (but not all) are wrote as negatives? Or am I mistaking the parentheses for projections? Thanks again!

I gather this is a complicated version of "find the slope given 2 points": (y2-y1)/(x2-x1)
sum(xy) - sum(x)* avg(y) is the equivalent of
sum(X squared) - count(x)*avg(x) squared is the equivalent of (x2-x1)


Why this is so can it be explained in words?

[rexelagapay]

question, sir. i noticed the actual figures have negative values. shouldn't be values always positive? because shouldn't it be that the values when plotted on a graph should form a trend line and that they should be positive. this is what i am thinking because the trend line is plotted on the positive quadrant of the graph. thanks.

How does 261.1 - 35.37 (5.5) gives us 66.5?
