Answer:
There's one unit assembled every 15 minutes
Step-by-step explanation:
There are no choices, but, from the given graph, we can analyse the relation of the variables and the constant ratio of change.
The constant ratios of change is defined as the quotient between the variability of the dependent variable (Time) and the variability of the independent variable (Number of Units), which is
[tex]m=\frac{\Delta y}{\Delta x}[/tex]
Now, we are gonna use two points on the line, which are (1,45) and (2,60). With these points we find the ratio of change, which is also the slope of the line
[tex]m=\frac{60-45}{2-1}=\frac{15}{1}=15[/tex]
As you can observe, the ratio is +15, that means the function is increasing.
Also, we can deduct that there's one unit assembled every 15 minutes, that's the relation between these variables.
