Question

Plz help me I don’t understand . I would appreciate if you help me .

Answer 1

Answer:

1a: A,D

1b: See the graph below

1c: Three solutions

2. y = 2x

Step-by-step explanation:

1a: Use elimination method to discard options

B) If x=4 then y=11, which is wrong.

C) If x= -1 then y=1, which is wrong.

The values in the table matches for y=2x+3.

1b: Substitutiong values in the respective equations, we get the following tables:  

x= -2, 0, 1 then y= 3, -1, 5

x=0, 1, 5 then y= 1/2, 0, -2

For the graph , you can see the figure shown.

1c: From the graph, it is clear that there are three solutions of these equations, namely (0,3), (0,1/2), (-1,1).

2: The graph of equation y=2x is parallel to the graph of y=2x+3 and hence, they will have no common solution.

Answer 2

1b.
To fill the chart..

X | -2 | 0 | 1 |
Y | -1 | 3 | 5
