Respuesta :
If the ratio of x/y or x/y is always the same constant, then a and y are directly proportional and the constant is called the constant of proportionality.
If the product of xy is always the same constant, then a and y are inversely proportional and the constant is called the constant of proportionality.
unit rates --- are like any rate found by dividing --- like speed --- miles per hour unit means 1 and this is miles traveled in one hour (at constant speed) --- so you just divide --- traveling 100 miles in 2 hours = 50 miles in 1 hour --- 50 miles per hour --- miles/hour <<< that is a unit rate
slope is a rate of change --- on an x-y coordinate axis graph the slope is the rate of change of y compared to a change in x --- this is not necessarily a unit rate ... slope of 2/3 means a change of 2 for y will create a change of 3 for x (not a change of 1, so it is not a unit rate)

Answer:
Table of Values: The ratio of (Y) to (X) gives the unit rate and slope.
Equation: If the equation can be written as y=mx, then m is the unit rate and the slope.
Graph: When the line passes through the origin, the slope of the graph gives the unit rate and the slope.
