Answers please, and explain if you don't mind.

Alright so the parentheses mean (x, y) so basically you have to plug in the numbers in parentheses into the equation so here's what I got:

a. i
b. iv
c. ii
d. v

So then e must be iii, let’s check:
y = -x + 1
.5 = -.5 + 1 ✔️
.75 = -.25 + 1 ✔️
.875 = -.125 + 1 ✔️

So that’s how you would solve those equations. Hope this helps.
