1) In the Line of Best Fit, what is the slope? Round to the nearest tenth if necessary

2)In the Line of Best Fit, what is the y-intercept? Round to the nearest tenth if necessary.

3)What is the full equation for the Line of Best Fit? Round to the nearest tenth if necessary. (No spaces in your equation must be in the form y=mx+b )

4)What is the correlation coefficient? Round to the nearest hundredth if necessary.

5)What type of correlation does the graph have?

6)find y when x is 17 (round o the nearest tenth)

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.

i believe it is 2
