Answer:
Driver 1 score: 9
Driver 2 score: 3
Step-by-step explanation:
We are given the following in the question:
The number of marks scored on a driving test are y(x) is a dependent variable and the number of drinks taken by the driver is the independent variable(x).
Slope, m = -3
y-intercept,c = 18
Then, we can write the regression equation as:
Driver 1 consumed 3 drinks.
We put x = 3 in the regression equation.
Thus, the predicted driving 1 score for driver 1 is
Driver 1 predicted score is 9.
Driver 2 consumed 5 drinks.
We put x = 5 in the regression equation.
Thus, the predicted driving 2 score for driver 2 is
Driver 2 predicted score is 3.
That is that correct answer because the y-intercept is the starting point!
Answer:
Step-by-step explanation:
Hello:
equation is the line is : y = ax+b a is a slope
y = (3/5)x+b
passing through the point (9;−4) : -4 =(3/5)(9)+b
b = - 4 -27/5 = -47/5
y = (3/5)x- 47/5
just g o o g l e it. i'm sure g o o g l e knows ... ... ... ....
See below for the proof of the equation
<h3>How to prove the equation?</h3>
The equation is given as:
Take the LCM
Expand
Evaluate the like terms
Rewrite as:
Factorize the numerator
Divide
2(a - b)= 2(a - b)
Both sides are equal
Hence, the equation has been proved
