Answer:
→ The table is:
→  x  →  -1   →  0  →  1
→  y  →  -3  →  0  →  3
The graph of the line is figure d
Step-by-step explanation:
∵ y = 3x
∵ x = -1, 0, 1
→ Substitute the values of x in the equation to find the values of y
∴ y = 3(-1) = -3
∴ y = 3(0) = 0
∴ y = 3(1) = 3
→ The table is:
→  x  →  -1   →  0  →  1
→  y  →  -3  →  0  →  3
∵ The form of the linear equation is y = m x + b, where
∵ y = 3x
→ Compare the equation with the form
∴ m = 3
∴ b = 0
→ That means the slope is positive, then the direction of the line must
    be from left tp right and passes through the origin
∴ The graph of the line is figure d
