Answer:
= (-2,5)
Step-by-step explanation:
To Find:
Solution :
Referring the given graph
We can find the coordinates of 
and 
Coordinates of = (-7,1)
Coordinates of = (5,4)
Thus Coordinates of = (-7+5,1+4) = (-2,5)
Thus = (-2,5)
So, the point = (-2,5) is shown on the attached graph file
to get the slope of any line, all we need is two points off of it.
so let's see hmmmmmmm this line passes through (0, 1) and hmmmm (4, -2)
Answer: 1.2 liters remain
1 liter = 1000 milliliters
if there’s two liters, that’s 2000 milliliters. the mom then poured 2 glasses each with 400 milliliters, or 800 milliliters in total. 2000 - 800 = 1200. 1200 milliliters converted into liters = 1.2 liters.
