The table shows the highs and lows in temperature over the last week in two towns in separate states. Which matrix shows the dif
ference in high and low temperatures between these two cities?
1 answer:
Answer:
see attachment
Step-by-step explanation:
If we assume that the matrix is populated with (difference of high temperatures) in the first row and (difference of low temperatures) in the second row, we only need to look for one value.
The difference between the Monday high temperatures is 35 - 26 = 9 degrees. We expect that to be in the first row of the first column of the matrix we're looking for. We find that matrix in selection D.

Answer:
The graph is attached Below and the plotting is given below.
Step-by-step explanation:
Given:
-9x + 6y = 18
Solution:
To draw a line on a graph the required minimum two points but here we will have three points as point A, point B, and point C.
For point A
Put x = -4 in the given equation we get
-9×-4 + 6y = 18
6y = 18-36
∴
∴ Point A ≡ ( -4, -3 ).
For point B
Put x = -2 in the given equation we get
-9×-2 + 6y = 18
6y = 18 - 18
6y = 0
∴
∴ Point B ≡ ( -2, 0 ).
For point C
Put x = 0 in the given equation we get
-9×0 + 6y = 18
6y = 18
∴
∴ Point C ≡ ( 0, 3 ).
Now we have Point A ,B and C join it and you will have Line.
