How can proportionality constant be determined from the best fit straight line graph?
उत्तर
Constant of proportionality can be determined from the best fit straight line by calculating the slope of the graph by using the formula.
Slope of graph = `"Difference between the co-ordinates on y-axis"/"for any two points on the graph line"`
= `"Difference between the co-ordinates on x-axis"/"for any two points on the graph line"`
