Answer:
y = 3x
Step-by-step explanation:
In this case we are just looking for a multiplier.Consider the values of x and y
x = - 2 → y = - 6 , that is y = 3 × x
x = - 1 → y = - 3, that is y = 3 × x
x = 1 → y = 3, that is y = 3 × x
x = 2 → y = 6, that is y = 3 × x
x = 3 → y = 9, that is y = 3 × x
Hence y = 3x ← is the equation relating x and y
