Which point is on the line 4y-2x=0?
hoa [83]
To figure this out, we just need to plug in the points.

4(-1) - 2(-2) = 0
-4 - (-4) = 0
-4 + 4 = 0
0 = 0 
True

The correct answer is a. (-2, -1).

Alexis has 36 marbles he gives 1/9 of marbles away to Sara. How may marbles did Sara have
sattari [20]
1/9 of total marbles = 1/9 × 36 = 4
so Alexis gave 4 marbles to Sara.
And so Alexis is left behind with 32 (36-4) marbles and so Sara have 4 marbles now
