Answer:

Strong Negative

Step-by-step explanation:

We already know that the answer is between c and d because the correlation coefficient negative.

We just have to figure out whether it is strong or weak.

In general, anything between -.7 and -1 is considered to have a strong correlation. -.8 is in between -.7 and -1 therefore the correlation is best described as strong negative.

What combination of transformations is shown below?
ozzi

the sequence is:

Translation, then reflection.

The correct option is the second one.

<h3>What combination of transformations is shown?</h3>

We start with figure 1.

In the image, we can see that the image is shifted 4 units up and 4 units left to make figure 2.

Then you can see that the image is reflected across a horizontal line to make figure 3, you can see that because now the "L" is facing upwards.

Then the sequence is:

Translation, then reflection.

The correct option is the second one.

Find an equation of the line that goes through the points (-9,-20) and (-8,-17). Write your answer in the form y = m x + b .
Oliga [24]

Answer:

y = 3x + 7

Step-by-step explanation:

First, we will solve for the slope (m).

The formula for slope is: m = \frac{y2 - y1}{x2 - x1}

m = \frac{-17 - -20}{-8 - -9} --- enter the points into the formula

m = \frac{3}{1} --- simplify

m = 3 --- simplify

Now we will solve for the y-intercept (b).

y = mx + b

y = 3x + b --- substitute the slope into the equation

-20 = 3(-9) + b --- substitute the x and y of either point into the equation

-20 = -27 + b --- simplify

7 = b --- add 27 to both sides

b = 7

Done.

y = 3x + 7
