Question

A.write an equation to model the relationship

b.explain how you know if an equation or a graph represents a proportional relationship ​

Answer 1

a) 12 · y = x

b) If the points show equivalent fractions and the line goes through (0,0)

Explanation:

a1) divide any numbers from the x and y line (for example, 2 ÷ 24 would give us 12)

a2) This equation makes sense because any number from the x line (for example, 2) multiplied by 12 would give us the number from the y line (in this example, 24).
