Question

verify whether x and y show direct variation. if yes then find k , x= 2,3,5,6 ,y = 6,9,17,20​

Answer 1

Answer:

Two quantities x and y show direct variation when y = kx, where k is a number and k ≠ 0. The number k is called the constant of proportionality. The graph of y = kx is a line with a slope of k that passes through the origin. So, two quantities that show direct variation are in a proportional relationship.
