What is a residual ?  
i) The difference between the y-value of a data point and the corresponding y-value from the line of best fit.
ii) Actual y-value minus predicted y-value.
iii) All the remaining points that the line of best fit did NOT touch.
iv) The ratio of how many data points are on the line vice not on the line.

Jhon draws a trend line for the scatter plot in item 3 and writes the equation y = 6.5x + 12 to represent the line. Use her equation to predict how much she will spend if she buys 7 books

Let . Suppose you subtract 5 from the input of the f to create the new function g, then multiply the input of the function g by 3 to create a function h. Write the equation that represents h?

If  is the transformation of   after a vertical compression by  , a shift right by 2, and a shift down by 4. What a function for .

>>>Vertical shift of f(x) by 3/4 becomes 3/4(x)
>>>Shifting right the function becomes 3/4(x-2)
>>>Shifting right the function gives 3/4(x-2)-4.
