Determine whether the graph represents a proportional relationship. A)Yes, it is a proportional relationship because the graph goes through the origin

B)No, it is not a proportional relationship because the graph does not go through the origin

C)Yes, it is a proportional relationship because the graph is a straight line

D)No, it is not a proportional relationship because the graph is not a straight line

their is no graph showing

step-by-step explanation:

the rate of change is 25

let

step

find the slope of the line ab

we know that

the formula to calculate the slope between two points is equal to

substitute the values

step

find the equation of the line ab with the slope m and point a

we know that

the equation of the line in the slope-point form is equal to

substitute the values

convert to function form

let

therefore

the answer is the option

see the attached figure to better understand the problem

step-by-step explanation:

assume that y=mx+n

you may see as , where

in we change places of numerator and denominator, then we insert an opposite sign

and substitute m=-1/3 in the equation y=mx+n

point (4,2), so we substitute x=4, y=2 to the equation and calculate

the answer is
