Jane took a survey of the ages and number of younger siblings students in her school have. She found a line of best fit for her data. Which r-value suggests a strong negative correlation for her line of best fit?
A. r = 0.97351
B. r = −0.27331
C. r = −0.97351
D. r = 0.27331

answer:

C.

Step-by-step explanation:

c has a umber closest to 1

answer: idk

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
