What is the Equation for a proportional relationship?

• $y=kx$

• $y=\frac{k}{x}$

• $y=\frac{x}{k}$

• $y=x$

What is the origin?

• $\left(1,1\right)$

• $\left(0,1\right)$

• $\left(0,0\right)$

• (-1,-1)

If a graph is proportional it will?

• Be curvy

• Be straight

• Be a circle

• Be zig-zag

How do you find the rate of change?

• The change in 'x' over the change in 'y'

• The change of 'y' multiplied by 'y'

• The change in 'x' multiplied by 'y'

• The change in 'y' over the change in 'x'

The number of trees and the number of apples are given in the table above.  Determine which statement below is correct.

• The table is not proportional because the unit rate is not constant.
• The table is proportional and the unit rate is 1/13
• The table is proportional and the unit rate is 13.
• The table is not proportional because it doesn't pass through the origin.
