Where are all the tutors at??? Like it won’t even let me ask a tutor

Answer 1

The scatter plot is given and objective is to find the best line of fit for given scatter plot.

Let's take the few points of scatter plot,

(0,8) ,( -1,8) , (-4,10) ,( -8,12),(-10,14) (-12,14)

Take the line and check which graph contains most of the points of scatter plot.

`1)\text{ f(x)=}(-1)/(2)x+8`

The graph is ,

now take ,

`2)\text{ f(x)=x+8}`

The graph is,

This graph contains only one point of scatter plot.

Take,

`3)\text{ f(x)= 10}`

Now the take the last equation,

`4)\text{ f(x)=-2x+14}`

this graph contains no point of the scatter plot.

From all the four graph of the lines it is observed that option 1) is the best line of fit for given scatter plot. because it contains 3 points of scatter plotes . which is more than the other graph of line.

Answer: Option 1)
