This question is asking only for the slope of the regression equation. This slope can be easily calculated using the following rule:
slope = SP / SSx
Examining the givens, we will find that both parameters are given where:
SP = 30 and SSx = 10
Substituting with the givens in the above mentioned equations, we can calculate the slope as follows:
slope = 30 / 10 = 3
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
To put this into slope-intercept form, you need to isolate/get the variable "y" by itself in the equation:
8x - 6y = 6 Subtract 8x on both sides
8x - 8x - 6y = 6 - 8x
-6y = -8x + 6 Divide -6 on both sides to get "y" by itself
The transformation used was a translation because the numbers changed. Since the x is becoming a smaller number the figure is moving to the left and since the y is getting larger the figure is also moving up. So the answer is: translation, 2 units to the left and 2 units up
Well it's hard to visually inspect this long text; let's look at it.
Based on visual inspection the averages look about the same.
Answer:
27,000
Step-by-step explanation:
$450,000 x 0.06= $27,000
0.06 is the 6% that you multiply by the total amount they earned to see how much they paid the realty company.
