Question

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

*insert attached picture here*

How much more would the value of y be on the graph than its value in the table when x = 12?

I added the y values for both until i got twelve and I subtracted the table's final y value from the graph's. I ended up with 410 but the only answer choices are:

150
300
450
600

What am I doing wrong?

Answer 1

relation (for left table ) is y=30x
so,

if x= 12, then y must be 12×30= 360

..,................

for the right graph,
relation is y=55x

if x= 12, then y= 12×55= 660

so y must be (660-360)= 300 more ! I guess the answer is 300 !

if you have any doubt, you can comment !
