Does a trend line need to pass through all the points in a scatter plot?

Anika [276]

Hi.

The answer is no/false, as long as all the dots in the scatter plot follow the generic pattern of the line, it is fine. The line does not need to touch the dots.

Write and equation of the translated or rotated graph in general form (picture below)

Svetlanka [38]

Answer:

Option b

Step-by-step explanation:

The equation $4x ^ 2 + 5y ^ 2 = 20$ has center in (0,0).

But the transformation $T(5, -6)$ shifts the center of the equation to the point (5, -6).

Therefore, when applying $T(5, -6)$ we will have the following equation translated.

$4(x-5) ^ 2 + 5(y - (-6)) ^ 2 = 20$ .

Simplifying we have:

$4(x-5) ^ 2 + 5(y + 6) ^ 2 = 20$

Now we expand $(x-5) ^ 2$ and $(y + 6) ^ 2$

$4(x ^ 2 -10x +25) + 5(y ^ 2 + 12y +36) = 20\\\\4x ^ 2 -40x + 100 + 5y ^ 2 + 60y + 180 = 20\\\\4x ^ 2 + 5y ^ 2 -40x + 60y +260 = 0$

The equation of a circle has the form

$h(x-a) ^ 2 + q(y-b) ^ 2 = r$

For h = 1 and q = 1.

If $h \neq 1$ and $q\neq 1$ then the graph becomes an ellipse.

In this problem h = 4 and q = 5 therefore the figure is an ellipse

Answer:

Add the two angles. The two number correspond to a part of the larger LMN angle, I think, so they should equal the total when combined, I think.
