If a trend line had the equationy=x+9 what y value would you expect bto obtain when x is 20

29

Once again sorry about reposting this question.

To determine the value of y when x is 20 using the equation y = x + 9, we can simply substitute x = 20 into the equation and solve for y.

Substituting x = 20 into the equation y = x + 9:
y = 20 + 9
y = 29

Therefore, when x is 20, the expected value of y is 29.
