What equation represents the proportional relationship displayed in the table?
KATRIN_1 [288]

Answer:

y=6x

Step-by-step explanation:

Given:

The table is given as:

x   0    4       7       8

y   0    24    42     48

The relationship between 'x' and 'y' is a proportional relationship.

A proportional relationship is one in which one variable varies directly with the other by a factor of 'k' also known as constant of proportionality and k\ne 0

A proportional relationship is given as:

y=kx

Now, we plug in 'x' and 'y' values and find the value of 'k'.

Let x=4\ and\ y=24

24=k\times 4\\\\k=\frac{24}{4}=6

Therefore, the constant of proportionality is 6. Hence the complete equation is given as:

y=6x
