Plz me i don’t understand . i would appreciate if you me .

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.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the first one

step-by-step explanation:

just id the test.
