How many solutions does this linear system of equations have? -3x + y = 4
9x – 3y = –12
1.Two solutions:x=12 and y=9
2.Infinite number of solutions
3.No solution
4.One solution: (3,6)

3x=y-3

Step-by-step explanation:

-3x+y=4

-4+y=hu

its a straight line parallel to the time axis

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
