Question

Two scatter plots have a positive trend. After drawing a trend line for each you realize that both scatter p? plots have exactly the same trend line. which of the following is false? both trend lines slope upward, as you move from left to right both trends lines have the same y intercept both trend lines have the same equation the scatter plot must be completely identical in appearance

Answer 1

It's positive, and thus has an upward slope. The slope, the trend line that is, is the same, and thus (1) the equation must be the same; which inherently means (2) the y-intercept is the same. What is (possibly and probably) different is the scatter plot itself

Answer 2

same slope does not imply same line

Answer 3

i assume the difference here is in how you interpret: "exactly the same trend line"

Answer 4

so anas post is valid ;)
