Answer:
A. 8x - 9y = -23
Step-by-step explanation:
(-4,-1) and (1/2,3)
We write the equation in slope intercept form y=mx+b
then we convert it into standard form
m is the slope and b is the y intercept
(-4,-1) and (1/2,3)
To find out b we plug in (-4,-1) and slope m value in y = mx+b
-1 = (8/9) (-4) + b
Add 32/9 on both sides
Take common denominator 9
So equation y = mx + b becomes
Standard form is Ax + By = C
To get standard form , multiply the whole equation by 9
9y = 8x + 23
Subtract 8x on both sides
-8x + 9y = 23
Multiply the whole equation by -1
8x - 9y = -23

water - water = water
0.72*60 - x = 0.68(60-x)
72*60 - 100x = 68*60 - 68x
-32x = -4*60
x = (1/8)60
x = 7.5 liters (amt of water to evaporate)</span>
