which equation can be used to describe the relationship between x and y shown in the table?

Answer:
y = 3x + 9
Step-by-step explanation:
y = mx + b
As the values of x increase by 1, the values of y increase by 3.
That means the slope, m, is 3.
m = 3
At x = 0, y = 9. That means the y-intercept, b, is 9.
b = 9
y = mx + b
y = 3x + 9
