Which graph of ordered pairs shows a proportional relationship? (Provide an explanation if you can! Thanks.)

1 and 4 i think they look proportional

Only the first graph

Step-by-step explanation:

In order for a equation to be proportional it has to have a straight line (which indicates that it has a constant rate of change.) and it has to go through the origin

If  you were to draw a line straight through the ordered pairs of graph 1 it would be a straight line and it would go through the origin (0,0)

therefore graph one would show a proportional relationship

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
