Answer:
A
Explanation:
the rate of change of y with respect to x.
that is the regular slope of the linear function, which is the ratio (y coordinate change / x coordinate change) when going from one point on the line to another.
from (5, 2) to (10, 3)
x changes by +5 (from 5 to 10)
y changes by +1 (from 2 to 3)
the slope or rate of change is
+1/+5 = 1/5
