∙ 6y agoIf the equation is y = kx then the constant of proportionality is k.
answer: 2.5 :)
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.
In a table, divide a number in one column by the corresponding number in the other column. In a graph it is the gradient of the line. The equation, for the variables X and Y will be of the form Y = mX and the constant of proportionality is m.
The linear function has the form y=mx+b, which I expect you have heard of. The 'b' is the y-intercept, and the 'm' is the slope. A constant of proportionality is something you have with direct variation, which is where the line goes through (0,0). This happens when 'b' equals zero. So now the equation is just y=mx, and the constant of proportionality is 'm'.

v = H0D Where v is the velocity at which a galaxy moves away from us, and D is its distance. With H0 being the constant of proportionality (the Hubble constant) between the distance D to a galaxy and its velocity v.
y = cx where c is the constant of proportionality.
y = kx where k is a non-zero constant is an equation of direct proportionality between x and y.

It's when the rate of change of distance per unit time is constant. Speed (or more precisely, velocity) is represented by the differential equation ds/dt, where s = displacement (actual distance travelled), and t = time taken
The equation for constant speed is distance = speed x time, where distance is the total distance traveled, speed is the constant speed at which the object is moving, and time is the duration of travel.
It is p2 = ka3where p is the orbital period, a is the semi-major axis of the orbit and k is a constant of proportionality.
