No. When you draw a best line of fit on the scattered plot, the line would not be straight.

Does a trend line always pass through every point on a scatter plot?

No, that would be quite unusual if if did, although not impossible.


If 16 points are arranged in a circle how many lines are needed to join every point to every other point once?

121


How can you tell from a scatter plot whether 2 variables have a positive correlation a negative correlation or no correlation?

Suppose the scatter plot is of a variable X on the horizontal scale and Y on the vertical scale.Find the approximate middle of the x values and call it p.Find the approximate middle of the y values and call it q.Draw horizontal and vertical lines through the point with coordinates (p, q).If you know about quadrants, skip this paragraph. The two lines through the point (p,q) divide up the plane into 4 quadrants. Quadrant I is top right. Quadrant II is top left. Quadrant III is bottom left. Quadrant IV is bottom right.If the scatter plot is mostly in quadrants I and III the correlation is positive. If mostly in quadrants II and IV the correlation is negative. Otherwise the correlation is small.Remember, though, that 0 correlation does not mean no relation. y = x2 will have 0 correlation but it is a perfectly well defined relationship!Suppose the scatter plot is of a variable X on the horizontal scale and Y on the vertical scale.Find the approximate middle of the x values and call it p.Find the approximate middle of the y values and call it q.Draw horizontal and vertical lines through the point with coordinates (p, q).If you know about quadrants, skip this paragraph.

To find a segment parallel to another segment and through a given point fold a piece of paper so that the fold goes through the point fold a piece of paper so that thefold goes through the point?

true


What is a point slope equation of the line with slope -12 that goes through the point (53)?

If you mean a slope of -12 through the point (5, 3) the equation is y = -12x+63
