The scatter plot shows the association between the ordered pairs
The two ordered pairs that can be joined to best draw the line of best fit for this scatter plot are (0, 13) and (10, 0)
<h3>How to determine the two best ordered pairs?</h3>To draw the line of best fit, the line must pass through at least two points such that the number of points on either sides of the line must be equal
See attachment for illustration
From the attached image of the graph, we can see that the line passes through the points (0, 13) and (10, 0), and there are 4 points on either sides
Hence, the two ordered pairs are (0, 13) and (10, 0)

Answer:
Step-by-step explanation:
The standard form for this function is
y = Asin(Bx - C) + D where
A is the amplitude,
B is used to find the period in the formula ,
C is used to find the phase shift in the formula ,
and D is the midline which either moves the function up or down from its natural midline of 0.
We have no given phase shift, so there is no C value. The amplitude is easy; we just fill in A as 4. The period is another story:
and we solve for B by cross multiplying:
3πB = 4π and
so
so the function is
