Please help with my 3 questions if you don't answer this, and do random stuff like the other guy im r3porting you ;p

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)

168

step-by-step explanation:

i am pretty sure that the answer is 168

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
