Answer:

b - any real number

Step-by-step explanation:

Parallel lines have the same slope.

We have the equation of a line in the standard form Ax + By = C.

Convert to the slope-intercept form y = mx + b

m - slope

b - y-intercept

$9x+3y=-22$ subtract 9x from both sides

$3y=-9x-22$ divide both sides by 3

$y=-3x-\dfrac{22}{3}$

Therefore we have the slope m = -3.

Put it to the equation of a line:

$y=-3x+b$ add 3 to both sides

$3x+y=b$

The answer is 0

Let's solve your equation step-by-step.

3(|v−3|)=9

Step 1: Divide both sides by 3.

3(|v−3|)3=93

|v−3|=3

Step 2: Solve Absolute Value.

|v−3|=3

We know either v−3=3orv−3=−3

v−3=3(Possibility 1)

v−3+3=3+3(Add 3 to both sides)

v=6

v−3=−3(Possibility 2)

v−3+3=−3+3(Add 3 to both sides)

v=0

Answer:

v=6 or v=0

Answer:

Strong positive correlation

Step-by-step explanation:

The given scatterplot, where the data points are sloping upward:

The stronger the association of the two variables, the closer the Pearson correlation coefficient, r, will be to either +1 or -1 depending on whether the relationship is positive or negative, respectively.

If the value of the correlation coefficient is 0 < r < 1 then there is a positive linear trend and the data points are scattered around the line of best fit; the smaller the absolute value of r, the less well the data can be visualized by a single linear relationship. The closer the value of r to 0 the greater the variation around the line of best fit.

In the attached screenshot, where I've drawn a line across the graph: it shows that the data points are clustered around the line. It is easier to estimate that the value of r is closer to 1, which implies a strong positive relationship between two variables. My estimate is that r = 0.8.

Therefore, the correct answer is Strong Positive association.
