Question

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

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 !
