Given that,
Point 1 = (-6,9)
Point 2 = (2,9)
To find,
The slope of a line that passes through the given pair.
Solution,
We have,
x₁ = -6, x₂ = 2, y₁ = 9, y₂ = 9.
The formula for the slope of a line is given by :

Hence, the slope of the line that passes through the given pair is 0.
Answer:
Dealer 2 is more efficient than Dealer 1.
Dealer 2 is the leading brand.
Step-by-step explanation:
The standard deviation for the combined assignment is 5 minutes.
To combine the standard deviations, we use:

With our information, we have:
Answer:
y = 5x - 21
Step-by-step explanation:
Since we already know the slope, all we need to do is plug the values of x and y into the equation.
y = 5x + b
-1 = 5(4) + b
-1 = 20 + b
-21 = b
The equation is y = 5x - 21.
