Ok so I’m making this poster for my teacher and it’s kinda very plain any suggestions?

1. Add more decor

2. Background music

3.Slide show

4. 1-10 reasons why she's the best teacher

5. Write a paragraph on how much you appreciate her.

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)

b. b < 1 might be the correct answer
