well, we see that it is a linear function.
so, we should make an equation that follows:
y = mx + b
b = y intercept, which is 0 because it connects at the origin.
m is the slope, which is rise/run.
we find a point at ( 0.7 , 0.5 ).
the rise is 0.5, and the run is 0.7, so we do
0.5/0.7
and we get 0.714285714285714, which we can round to 0.7143 for the m.
we have everything we need.
so,
y=0.7143x
(the b is 0, so we don’t have anything else to add).
hope this helped!
