Answer:
we know that
the equation for calculating the slope of a line is
m=(y2-y1)/(x2-x1)
look for any two points on the graph
let
A(0,0)
B(3,1)
m=(1-0)/(3-0)------> m=1/3
the slope is 1/3 throughout the line
therefore
the answer is the option
B-It is 1/3 throughout the lineStep-by-step explanation:
