Answer:
2x-3y=9    and    4x-6y=30
Step-by-step explanation:
hello :  
note y=(2/3)x+5  no y=23x+5
2/3 is the slope....... all lines parallel to this line has same slope.
1)   2x-3y=9   means : 3y = 2x-9   divide by 3 : y=(2/3)x-3..same slope.
2)  4x-6y=30  means : 6y= 4x-30 divide by 6 : y=(4/6)x -30/6
but 4/6 = 2/3 so : y=(2/3)x-5..same slope.
