A=k/B where K is the constant or factor. Relationship remains unchanged.]]> 2018-10-30 04:23:24 UTC https://padlet.com/kathy_cruz/oo5spoww5yvs/wish/298349609 kathy_cruz https://padlet.com/kathy_cruz/oo5spoww5yvs/wish/298349634 Finding what makes up a unit. Example Red Trapezoid was worth 1 unit. Or the example in the video, the unit was different dependent upon the interpretation. All have to agree to what makes up one unit.]]> 2018-10-30 04:23:40 UTC https://padlet.com/kathy_cruz/oo5spoww5yvs/wish/298349634 kathy_cruz https://padlet.com/kathy_cruz/oo5spoww5yvs/wish/298349668 Looking at the relationships. Focusing on the ratio. Comparing quantities. Multiplicative comparison.]]> 2018-10-30 04:23:57 UTC https://padlet.com/kathy_cruz/oo5spoww5yvs/wish/298349668 kathy_cruz https://padlet.com/kathy_cruz/oo5spoww5yvs/wish/298349698 y=mx 
This relationship shows that as x intercept increases so does y. This is considered a linear function.  The ratio is a direct proportion.For example, time and money.
