The regression equation given to us is y = 0.5x + 1.3
It is in the form y = mx+b
m = 0.5 is the slope
b = 1.3 is the y intercept
The slope of 0.5 indicates that each time x increases by 1, the value of y will increase by 0.5 (since 0.5 = 0.5/1)
Translate this into the context of the problem and that means "for every extra person attending (x), the prep time increases by roughly 0.5 hours" which is what choice C is saying, well a paraphrase of it anyway.
Answer: Choice C
Are there options for me to analyze from?
Answer:
There are no values of x that make the equation true
The system has no solution
Step-by-step explanation:
we have
![x+4=x+8](https://tex.z-dn.net/?f=x%2B4%3Dx%2B8)
Solve for x
Subtract x both sides
![x+4-x=x+8-x](https://tex.z-dn.net/?f=x%2B4-x%3Dx%2B8-x)
-----> is not true
therefore
Is a inconsistent system
There are no values of x that make the equation true
The system has no solution
Simply use the numbers to give a fraction
