Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:

We have two points (-5, 5) and (4, 2).
substitute:

Put the value os a slope and coordinates of the point (4, 2) to the equation of a line:

<em>add 4/3 to both sides</em>

Answer: A, B and E
Step-by-step explanation:
A residual values should be equally and randomly spaced around the horizontal axis. If the plot looks like any of the images in C and D, then the data set is probably not a good fit for regression. A non-linear pattern is more appropriate.
Answer:
Step-by-step explanation:
U just set that as an equation. So it would be like this... 3x+3= 63.
3x + 3 = 63
-3 - 3
3x = 60
/3 /3
X = 20
