Ascatterplot has a positive, linear correlation. which statement is true about the relationship between the x- and y-values? a. as the x-values increase, the y-values tend to increase. b. as the x-values increase, the y-values tend to decrease. c. as the x-values decrease, the y-values tend to increase. d. as the x-values decrease, the y-values tend to vary randomly.

Hence, option: A is the correct answer.

A. As the x-values increase, the y-values tend to increase.

Step-by-step explanation:

It is given that:

A scatterplot has a positive, linear correlation.

By positive we means that as the x-value increases the y-value also keeps on increasing and by linear relation we mean that it increases somewhat by a constant amount so that the we get a line of best fit.

Hence, the statement which  is true about the relationship between the x- and y-values is:

A. As the x-values increase, the y-values tend to increase.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
