Using correlation coefficients, it is found that a coefficient of -1 represents a strong negative correlation.
<h3>What is a correlation coefficient?</h3>
- It is an index that measures correlation between two variables, assuming values between -1 and 1.
- If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
- If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
For this problem, we have a correlation coefficient of -1, hence it means that:
- The relation is negative, as -1 is a negative number.
- The relation is strong, as the absolute value of the coefficient is of 1, which is greater than 0.6.

Answer: ![y= x-8](https://tex.z-dn.net/?f=y%3D%20x-8)
Step-by-step explanation:
- Slope intercept form has a general formula of
![y=mx +b](https://tex.z-dn.net/?f=y%3Dmx%20%2Bb)
- m represents the slope of the line
- b represents the value of the lines y-intercept
- the equation must be rearranged into the general formula by isolating for 'y'
![y-x=-8](https://tex.z-dn.net/?f=y-x%3D-8)
- to remove the x from the left side of the equation the opposite operation must be done to both sides
![y-x+x=-8+x](https://tex.z-dn.net/?f=y-x%2Bx%3D-8%2Bx)
- the negative and positive x cancel out on the left side, leaving us with the equation with y by itself
- now you can rearrange to put the equation into
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Final Answer: ![y=x-8](https://tex.z-dn.net/?f=y%3Dx-8)
