0.13 meter is same as 130 mm
Hope this helped and have a great day!
Slope intercept form is y = mx + b where m is slope and b is y intercept.
The line crosses the y axis at y = 4
The slope is 4/3
So the answer is y = (4x/3) + 4
It seems you double the amount each day. keep doing that until you get to 15
