Tap to calculate

Find the ratio for each row to see if the table shows a proportional relationship.

Ratio
{{row.x}}
{{row.y}}

Are these ratios constant?

Slide to plot points

Plot 3 points for the equation

012345
{{s2.maxY}}0
Current Point
({{s2.slider}}, {{s2.slider * s2.k}})
x=

Proportional relationships always form a straight line through the origin (0,0)!

Drag to calculate

Find the constant of proportionality by dividing by .

({{s3.px}}, {{s3.py}})
x (Time)
y (Distance)
{{num}}
{{s3.droppedY}} y
{{s3.droppedX}} x

Find the Equation

Read the scenario and select the correct equation

A robot assembles {{s4.y}} widgets (y)
every {{s4.x}} minutes (x).

First, find , then pick the equation!
