Proportional Relationships

Master proportional relationships & constant of proportionality (k) with this math practice worksheet!

Sort the following items into one of the following three categories: Proportional, Non-Proportional, or Both Proportional Non-Proportional. The "Both" category is for those characteristics that are true about both proportional relationships and non-proportional relationships. Proportional goes through (0, 0) y = -5x y is the same # Non-Proportional does not go through (0, 0) y = 3x + 10 y changes Does this table show a proportional relationship? Why?READ ALL OPTIONS AND SELECT THE CORRECT ONE(s). Yes, it starts at (0,0) Yes, it goes up by the same amount each time No, the change in y over the change in x is not constant No, y over x is not constant Does this table show a proportional relationship? Why?READ ALL OPTIONS AND SELECT THE CORRECT ONE(s). No, it does not start at (0,0) Yes, it goes up by the same amount each time Yes, the change in y over the change in x is constant No, y over x is not constant Does this table show a proportional relationship? Why?READ ALL OPTIONS AND SELECT THE CORRECT ONE(s). No, it does not start at (0,0) No, y over x is not constant Yes, the change in y over the change in x is constant Yes, y over x is constant No, there cannot be negatives in a proportional relationship Does this table show a proportional relationship? Why?READ ALL OPTIONS AND SELECT THE CORRECT ONE(s). No, it does not start at (0,0) No, y over x is not constant No, the change in y over the change in x is not constant Yes, y over x is constant No, it is not going up by the same amount each time Fill in the blanks. The general equation for proportional relationships is y=kx, where k is the constant of proportionality. Therefore constant of proportionality is found by calculating y divided by x. Fill in the blank. Given the equation y=-4x, then k must be -4. What is the constant of proportionality for this graph? 1 1 3 6 What is the constant of proportionality for this table? 5 3 1 1
