Find Slope Using Table of Values for Proportional Relationships

Which statement best describes the relationship of x and y in the table? Hint: Find the ratio between y and x. If it is constant, that value is the Constant of Proportionality (AKA: Unit Rate) and the relationship is proportional. You can determine if it is constant by dividing y by x for every (x,y) pair. Money/Hours. (k=y/x) If the quotient is the same for every ratio of y/x, then the relationship is proportional and the quotient is the Constant of Proportionality.

Write the equation for the table. Find the Constant of Proportionality. (k=y/x; k represents the Constant of Proportionality) Then, put it in the form y=kx. *REMEMBER: k is the Constant of Proportionality.

• y = 1/3x

• y = 3x

• y = 1/2x

• x = 3y

Is this table proportional or non-proportional?

• Proportional because the y to x ratio is a constant of proportionality. 

• Non-Proportional because the y to x ratio is not a constant of proportionality. 

• Proportional because the x to y ratio is a constant of proportionality. 

• Non-Proportional because the x to y ratio is not a constant of proportionality.
