The table and the graph below each show a different relationship between the same two variables, x and y:
olga2289 [7]

The value of y will be 60 so the correct answer is option C.

<h3>What is a graph?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

There is a linear relationship between the two variables x and y. For the given data in the table as well as in the graph. The expression for the two variables will be written in the form of an equation as follows:-

The expression for the data in the table:-

y = 25 x now at x = 12

y = 25 x 12 = 300

The expression for the values in the graph:-

y  = 30x at x = 12

y  = 30 x 12

Y = 360

How much more would the value of y be on the graph will be calculated as:-

Value  = 360 - 300

Value = 60

Therefore the value of y will be 60 so the correct answer is option C.
