What’s the answer to question 1,2,3,4?

1. y=0

2. y=2

3. y=4

4. y=-2(-4)-4

=32

y = 2x

x = 0

y = 2*0 = 0

0

x = 1

y = 2*1 = 2

2

x = 2

y = 2*2 = 4

4

y = -2x - 4

x = -4

y = -2*-4  - 4 = 8 - 4 = 4

4

Step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
