Which graph represents no solution

D. Parallel lines

Step-by-step explanation:

Lines which intersect have their point of intersection as the solution to the system of equations. If there is no solution then two lines do not intersect. The two lines must be parallel.

M=3/4J or J=4/3M

Step-by-step explanation:

3:4, 9:12, and 15:20 are ratios that are equal to each other.

If you multiply 3:4 by 3 you get 9:12 and if you multiply it by 4 you get 15:20

another way to check is to plug the numbers in.

3 is 3/4 of 4

9 is 3/4 of 12

15 is 3/4 of 20

so the equation is true
