Answer:
12) y=25x
13) 14 gallons
Step-by-step explanation:
m= (y2-y1)/(x2-x1)
m= (75-50)/(3-2)
m=25/1=25
y-y1=m(x-x1)
y-75=25(x-3)
y-75=25x-75
y=25x
------------------------------------
350=25x
x=350/25
x=14

<span>A system of equations has infinitely many solutions when the two lines representing the equations coincide. i.e. the two equations are the same.
2y - 4x = 6
2y = 4x + 6
2y = 2(2x + 3)
y = 2x + 3
-y = -(2x + 3)
-y = -2x - 3
Hence the other equation is -y = -2x - 3
