Question

Which equation of a line of best-fit reflects a negative correlation?

Answer 1

you are correct. you are looking for a negative slope. y=mx+b where m is the slope.
1/70=+
-83/-27 = 83/27=+
8=+
-6=-

Let me know if you have questions.

Answer 2

Answer:

we choose d

Step-by-step explanation:

Negative correlation occurs when the two variables in the equation shows a negative relationship to each other. If the independent variable increase the dependent one will be decreased. It means the slope of the equation is smaller than 0, (negative)

The standard linear equation is:

y = mx + b

In 4 answers, only d has negative slope = -6

So we choose d
