M = Y / X

m = [1 - (-2) ] / [2 - (-2)]

m = (1+2) / (2+2)

m = 3 / 4

Using (2,1)

y - yo = m (x-xo)

y - 1 = 3/4 (x-2)

Or

(-2,-2)

y + 2 = 3/4 (x+2)

Answer:

2 gallons of pure alcohol

Step-by-step explanation:

Let x represent the number of gallons of pure alcohol needed, and create an equation:

4(0.25) + x(1) = (x + 4)0.5

1 + x = 0.5x + 2

x = 0.5x + 1

0.5x = 1

x = 2

So, 2 gallons of pure alcohol should be added.
