Question

1-6. Indicate whether each table or graph represents a proportional

relationship or a non-proportional relationship.

pls answer! nobody answer right and I am sick of failing this is for a mastery

Answer 1

Explanation:

Proportional relationship means,

x ∝ y

x = ky

`(x)/(y)=k` where 'k' is the proportionality constant.

From table (1),

`(1)/(5)=(2)/(9)\\eq \text{Constant}`

Therefore, relationship is not proportional.

From table (2),

`(1)/(6)=(3)/(18)=\text{constant}`

True.

So the relationship will be proportional.

From table (3),

`\frac{\text{hours}}{\text{Miles}}= (2)/(110)=(5)/(175)=(1)/(55)`

Which is constant.

Therefore, relationship will be proportional.

From table (4),

`\frac{\text{Hours}}{\text{Paid}}=(3)/(29.25)=(5)/(48.75)=0.103`

Which is constant for every term.

Therefore, relationship will be proportional.
