Answer:
Step-by-step explanation:
A linear function has the following format:
In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.
Rate of change of 3
This means that
So
A solution at (6, 12).
This means that when x = 6, y = 12. So
The linear function is:
3/4*3/3=9/12
Hope this helps
