Answer:
a) 10mm each second.
b) 2 in a increasing correlation.
Explanation:
a) we want to look at 1 and 2 seconds to recognise the increase.
1 second it reachs 10mm
2seconds it reachs 20mm
20mm-10mm=10mm
This means each second its increasing by 10mm
B) Rise / Run
our two coordinates will be (1,10) and (2,20)
the run is when it goes across, which will be 1
and the rise will be 2
