Direct proportions may be represented by a straight line through the origin, with the equation y = kx. The gradient of the line is the constant of proportionality and is a measure of the change in the "dependent" variable for a unit change in the "independent" variable. In the case of an inverse proportionality, the graph is a hyperbola with the equation y = k/x. The constant of proportionality, k, is a measure of the change in the reciprocal of the "dependent" variable for a unit change in the "independent" variable.
A straight line with a positive slope, passing through the origin.
A straight line through the origin, and with a positive gradient (sloping from bottom left to top right).
If the points lie on a straight line through the origin, the two variables are in direct proportion.
Directly proportional. Greater speed - greater distance.
The answer is proportional.
For proportional relationships the ratio is a constant.
Do all linear graphs have proportional relationship
a proportional relationship means that it is contributed equally into other parts or quantities
the ones between the two fat people you just looked at
A Linear relationship is a relationship where variable quantities are proportional with each other.
Either a straight line through the origin or a hyperbola.
