Step-by-step explanation:
the slope of a line is expressed as y/x ratio, indicating how many units y changes, when x changes a certain amount of units when going from one point to another.
I see 2 interesting points with their coordinates being seemingly whole numbers :
(0, 8) and (4, 9)
between these 2 points x changes +4 units (from 0 to 4), and y changes +1 unit (from 8 to 9).
so, the slope is +1/+4 = 1/4
