The equation of the line of best fit of a scatter plot is y = 7x − 9. What is the slope of the equation?

−9, −7, 7, 9

Verified Answer :

I love math. Well the formula is y=mx+b. the slope is m so the answer is 7 

Answer:

Slope m = 7.

Step-by-step explanation:

Given :  y = 7x − 9.

To find : What is the slope of the equation.

Solution : We have given that y = 7x − 9.

On comparing with y = mx + b

Where, m slope of the line and b = y intercept.

Then slope of y = 7x − 9.

m = 7 and y intercept = -9.

Therefore, Slope m = 7.
