Each graph below shows a relationship between x and y.For each graph, determine whether x and y are proportional.If x and y are proportional, fill in the blank with a number in simplest form.Graph 1y12345678910x123456789100 Proportionaly is timesx Not proportionalGraph 2y12345678910x123456789100 Proportionaly is timesx Not proportionalGraph 3y12345678910x123456789100 Proportionaly is timesx Not proportional

Graph the line that passes through the coordinates shown and determine which statement is true. A. The line that passes through the given coordinates represents a proportional relationship because the line passes through the origin. B. The line that passes through the given coordinates does not represent a proportional relationship because the line passes through the origin. C. The line that passes through the given coordinates does not represent a proportional relationship because the line does not pass through the origin. D. The line that passes through the given coordinates represents a proportional relationship because the line does not pass through the origin.

If y is directly proportional to x2, and y = 2 when x = 1,what is the value of y when x = 5? y =

The third proportional to x2-y2, x-y is?x+yx-y(x – y)/(x + y)1

The graph shows the distance George traveled over a period of time.    Mark's Road TripDistance (miles) Time (hours) What is the constant of proportionality that relates the number of miles George traveled, y, to the time it took him to travel those miles, x? ResponsesA 12 miles per hour12 miles per hourB 18 miles per hour18 miles per hourC 24 miles per hour24 miles per hourD 36 miles per hour36 miles per hour
