A linear regression was used to determine the linear relationship between the sales of Gulp Milk and the average price for milk across its competitors. If the average competitor price rises or falls, but all other factors remain equal, including the price of Gulp Milk itself, what kind of slope coefficient do we expect to find for this relationship?

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
