Find the slope of any two ordered pairs (x,y):
For example let's take (1, 0.165) and (2,0.330)
m=(y2-y1)/(x2-x1),
then, substitute in the formula and you'll get
m=0.165
then substitute in the point-slope formula: y-y1=m(x-x1), you can use any of the ordered pairs, it doesn't matter you'll get the same result.
y-0.165=0.165(x-1), expand: y-0.165=0.165x-0.165
simplify: y=0.165x-0165+0.165...y=0.165x
your answer is y=0.165x , hope this can help you to solve other problems:)

Let
y = growth in inches
x = days
if follow y = mx + b
then (y2 - y1)/(x2 - x1) = (y4 - y3)/(x4 - x3)
pick any 2 pairs of coordinates & you should get m = 0.165
use 0 days with slope m then you figure out b is 0
So
y = 0.165x

A plot may help you decide....
considering your inability to answer this i would imagine you are in a basic course...
fit a straight line.

this is the pattern
each day the growth goes up by 0.165 see
0.165
+0.165
________
0.330
+0.165
________
0.495
etc thats how you answer it i dont understand what you mean by put it in an equation

It looks linear.
G = d(.165)

y= 165x
y being growth
x being days
