Which table has a constant of proportionality between y and x of 1.5

C

Step-by-step explanation:

In a proportional relationship the constant of proportionality k is

k =

Check this ratio for each of the values

A

= 1.5 , = 1.5 , = 1.4347.... ← Thus not A

B

= 1.1875 ← Thus not B

C

= 1.5 , = 1.5 , = 1.5

Thus the table with k = 1.5 is Table C

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
