(-3, 1.5)....simply add the x coordinates together, divide them by two, and then do the same for the y coordinates.
What is the relationship between RR' and SS'?
30+3
11*3
10*3+3
60-30+3
(sorry if these didn't help i'm a beginner and i'm in 7th grade)
F(x) is the same as y.......so basically ur subbing in ur points into the equation to see if it comes out equal.
f(x) = 3 - 2x.....(-2,-1)....x = -2 and f(x) = -1
-1 = 3 - 2(-1)
-1 = 3 + 2
-1 = 5.....this is not true, so it is not a solution
and that is how to do this problem.....
(-1,5)......this IS a solution
(0,3)......this IS a solution
(1,0)...this IS NOT a solution
(2,-1)...this IS a solution
