Use the Desmos Interactive Linear Regression. Find the regression equation and correlation coefficient.
Recall that the linear regression command in Desmos
after entering the table of values is "y1 - bx1 + d".
Least-Squares Regression Line:
Correlation Coefficient:

Least-Squares Regression Line:

y ~ –0.741505x + 19.6784

Correlation Coefficient:

r = –0.9777

Step-by-step explanation:

Did it on edge and got it right

the answer is 31.27mph

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
