The constant of proportionality between y and x will be 2/3. Then the correct option is C.
What is a linear equation?
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
From the graph, the rise is 2 and the run is 3.
Then the slope will be 2/3.
Then the equation of the line passing through the origin will be
y = 2x / 3
The constant of proportionality between y and x will be 2/3.
Then the correct option is C.
