Question

Please tell me if these answers are correct:

1. Is ( 0, 3) a solution to the equation y = x + 3?

Yes
No

2. Is ( 1, -4) a solution to the equation y = -2x?

Yes
No

3. Look at the following points:

( 4, 0)
( 3, -1)
( 6, 3)
( 2, -4)

Which are solutions to y = x - 4
(2 correct answers)

A. ( 6, 3)
B. ( 4, 0)
C. ( 3, -1)
D. ( 2, -4)


4. Give an example of an open equation




5. How can you use an equation to make a prediction from a pattern?



6. Pizza costs $1.50 per slice. Use a table and an equation to represent the relationship between the number of slices of pizza bought and the total cost.


I think
1. Yes
2. No
3. ( 4, 0) and ( 3, -1)

4. Well, an algebraic open equation (also known as an open sentence) is a mathematical equation that is neither true nor false. so an example of an open equation could be x + 3 = 7 or 2x = 12

6. y=1.50x; y=total number of slices x= the amount of slices 1.50=the cost of one slice

Answer 1

correct on 1,2,3,4,
6. No.
totalcost=numberslices*1.50
5. the equation gives the relationship between one variable and another.

Answer 2

1.A
2.B
3.B,C
4.B

Answer 3
