Answer:
y=78
Step-by-step explanation:
y=13(x-4) 2-4
y=(13-52) -2
y=(-24+104)
y=78
It is 40 40. 40 is the answer
Answer:
Im in 7th grade and I need some help on a math problem. can I post it?
We are given a line with the following data:
r-value = 0.657 (r)
standard deviation of x-coordinates = 2.445 (Sx)
standard deviation of y-coordinates = 9.902 (Sy)
We are asked to find the slope of the line up to 3 decimal places.
To find the slope of the line, based on the data that we have, we can use this formula:
slope, b = r * (Sy / Sx)
substitute the values to the formula:
b = 0.657 * ( 9.902 / 2.445 )
Solve for the b.
Therefore, the slope of the line is
b = 2.66078, round off to three decimal places:
b = 2.661 is the slope of the line.
