Answer:
It cannot be the line of best fit because it is not closest to most of the points; and (0, 15) and (10, 1)
Step-by-step explanation:
A screenshot of the first question is attached.
Graphing the points and drawing the line that is supposed to be the line of best fit, we can see that it is not very close to the majority of the points. This means it should not be used as the line of best fit.
For the second question, if we graph the points and draw a line between the first two, we get the second screenshot I've attached. It goes through the majority of points. However, if we draw a line through any of the other pairs of points, it does not go through the majority of points and thus would not be a line of best fit.
If y=4x+2 and x=1, we can get 4*1+2=6 for y, resulting in 1*6+1/6=2+z. Subtracting 2 from both sides, we get 4+1/6=z
