Answer:
There is a strong negative relationship between x and y
Step-by-step explanation:
we know that
The correlation coefficient r measures the direction and strength of a linear relationship. It can take a range of values from +1 to -1.
Values between 0.7 and 1.0 (-0.7 and -1.0) indicate a strong positive (negative) linear relationship
In this problem
The correlation coefficient for the data is −0.9847
therefore
Is a strong negative correlation
4x+28 +6x -15=-7x +64
10x+13=-7x +64
10x-7x=64-13
3x=51
x=17
I hope I helped you=)
Hi there!
The line is in slope-intercept form. This is y=mx+b, where b is the y intercept. Thus, because it is in this form, we can see that the y intercept is 3.
Now, for the x intercept. The x intercept is at y=0. Thus, we can just set y equal to 0 and solve for x.
0=-7x+3
-3=-7x
x=3/7
Thus, the x intercept is 3/7.
Our two answers are - x intercept = 3/7, y intercept = 3
Hope this helps!
