2- x= -2 y= -1 so the slope is -1/-2
3- x= 2 y= 3 so the slope is 1 1/2
i’m not sure if this is right but i’m learning this as well
8 thousands is equal to 8000.
15 hundreds is equal to 1500.
15 tens is equal to 150.
18 ones is equal to 18.
So just add them up.
8000 + 1500 = 9500.
9500 + 150 = 9650.
9650 + 18 = 9668.
The number is 9668
-1 is your answer.........
