Well to make a scatter plot you have to make a table first and record all your data. then plot the points and draw a line between exactly the same amount of points. there should be 5 on top and 5 on the bottom of the line. for the last question say what I said
Answer:
∠1 and ∠2
angles on a straight line add up to 180
Question:
Use technology to approximate the solution(s) to the system of equations to the nearest tenth of a unit.
Select all that apply.
(3.6,0.6)
(-2.6,0.4)
(-3.6,0.6)
(2.6,0.4)
(4.5,-1.5)
Answer:
Option A : 
is the solution to the system of equations.
Option D: 
is the solution to the system of equations.
Explanation:
The two equations are and
To determine the solution of the system of equations using technology, let us plot the equations in the graphing calculator.
The solution of the system of equations is the intersection of the two lines.
Thus, from the graph, we can see that the two lines f(x) and g(x) intersect at the points 
and 
Rounding off the solution to the nearest tenth, we get,
and
Thus, the solution to the system of equations is and
Hence, Option A and Option D are the correct answers.
Answer:
Step-by-step explanation:
To get from the top square to the bottom square, multiply by - 3 So the middle position of the bottom square is - 30. If you solve all of the top square, you can get the bottom square easily enough.
The diagonal of the top square adds to 13 + 10 + 7 = 30
The top line of the top square must add to 30 as well 13 + 11 + 6. Put 6 in the middle position.
The right hand vertical line must add to 30. 11 + 7 + 12 = 30
The middle row must add to 30. 10 + 12 + 8. 8 goes in the left position of the middle row.
Let's summarize what we have so far.
13 6 11
8 10 12
7
We can fill in the last two spaces by adding to 30
13 6 11
8 10 12
9 14 7
That completes the top magic square.
To get the bottom magic square, multiply by -3
- 39 - 18 -33
-24 -30 -36
-27 -42 -21
