test the residuals of two other points to determine how well the line of best fit models the data.

st three points are green, yellow and red

2nd three point are green yellow and upward green

Step-by-step explanation:

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

5x+10 is the correct one

hope this
