Question 249679
What do you notice if you divide the first by 3 and the second by 2?
correct they are the same
if you solve those two equations for y you will see that
 4x+6y=10
6y=10-4x
y=10/6-4x/6
y=-2x/3+5/3

6x+9y=15
9y=15-6x
y=15/9-6x/9
y=-2x/3+5/3
They are  equivalent equations with the same points
So answer c is correct
