Answer:

Step-by-step explanation:
The given data table is
x : 4 7 10 12 13
y : 5 7 12 14 18
We need to find the equation of the best fit line.
The general form of a best fit line is
.... (1)
where, m is slope and b is y-intercept.


Using the graphing calculator we get


Substitute m=1.383 and b=-1.526 in equation (1).

Therefore, the equation of best fit line is
.
Answer:3.1042, 3.209, 3.24, 3.4
Step-by-step explanation:
Answer:
y=5x
Step-by-step explanation:
From (2,10) you rise 25 in the y direction and run 5 in the x direction to get to the next known point (7,35).
Thus, the slope is y=25/5x AKA y=5x
