Question

In the least-squares line y = 5 − 9x, what is the value of the slope?

Answer 1

Just convert to standard form using Ax + By = C = -(A/B) where A = -9 and B = 5.
m = -9/1 which translates to -9.
Our slope is -9.

Answer 2

Answer:

Slope= -9

Step-by-step explanation:

Remember that functions in the form of the slope are represented like this:

Y=mx+c

The function that is given to us just moves C of place, and the m is the number that is located right aside of the variable x, so the slope is -9, this is how much would the graph will grow or decrease with the increase on the value of the variable x.
