If a trend line had the equation: y=x+9 what y value would you expect to obtain when x is 20??
20 + 9 = 29 still
Sorry i reposted question like i said below but thank you sorry for the inconvience.
To find the y-value when x is 20, you can use the given equation of the trend line, which is y = x + 9. Simply substitute x = 20 into the equation and solve for y.
Substituting x = 20:
y = 20 + 9
y = 29
Therefore, when x is 20, the expected y-value would be 29.
