Answer: okay so your problems are like 10000000k through  out resons of dum. so x=-1. is a little wrong becayse the x = into a 1 so  you make the 1 that factor. so thats why answer for 2.5

1. 4n + 28 
2. 30-10x
3. 3m+3n
4. 8+2j
        
             
        
        
        
We assume data and prediction as question is incomplete 
Answer and Step-by-step explanation:
Least squares regression line equations are used to model the relationship that exists between two variables, dependent and independent variables. The equation has the form y=a+bx where y is the dependent variable and x is independent variable, a is a constant and is the y intercept and b is the slope of the line. This relationship is then used to predict future outcomes.
Given that data for 2004-2005 for the basketball players are :
James- 20 points
John- 30 points
Chris- 50 points
Dave-15 points
Donaldson- 32 points
Richard -40 points
We predict the scores/points for James (for example) for the following year using the equation of the regression line y=0.79x+1544
We substitute his points x=20 I'm the equation:
Y=0.79*20+1544
=1599.8
The predicted value is 1599.8
