y=7-x
x + y= 500
120x + 35y= 500
(35+120) (x + y)= 500
35x + 120y= 500
Answer:
C. (2, 15) and (4, 9)
Step-by-step explanation:
The line of best fit in a scatterplot is a straight line that shows the relationship among the data. It is drawn in such a way that it groups the points evenly on each side of the line. It is used when a straight line could not be drawn through all or major number of points plotted on the graph.
From the question, when points (1, 16), (2, 15), (3, 14), (4, 9), (5, 8), and (6, 1) are plotted on a graph, the line of best fit would go through points (2, 15) and (4, 9). This would achieve an even spread of the points on the two sides of the line.

Option C: 3 units is the length of DA
Explanation:
The coordinates of a polygon ABCD are
We need to find the length of DA
The length of DA can be determined using the distance formula,
Let us substitute the coordinates and in the distance formula, we get,
Subtracting the terms within the bracket, we have,
Squaring the terms, we get,
Adding the terms, we have,
Thus, the length of DA is 3 units.
Hence, Option C is the correct answer.
so the ans is of last option.
