Divide each length over its corresponding width

16/9 = 1.77777777777778
20/11.25 = 1.77777777777778
24/13.50 = 1.77777777777778
The decimal results are approximate. The 7's should go forever

Since we get the same result each time (1.77777777777778), this means that the lengths and widths are proportional to each other.

Answer:

Yes, there is  a proportional relationship, because the ratio length/width is the same for all cases

Step-by-step explanation:

If the ratio length/width is the same for all cases, then they are proportional between them.

16/9 ≈ 1.78

20/11.25 ≈ 1.78

24/13.50 ≈ 1.78

Another way is to prove that they are proportional is to multiply and divide 16/9 by a constant, as follows:

16/9 = 16/9 * 1.25/1.25 = (16*1.25) / (9*1.25) = 20/11.25

16/9 = 16/9 * 1.5/1.5 = (16*1.5) / (9*1.5) = 24/13.5

Sloope intercept form is
y=mx+b
m=slope
b=y intercept =where the line passes through the y axis

we are given
line M has slope of 1 and passes through y axis at -2 (y intercept=-2)
equaton is therefor y=1x-2 or y=x-2


line N has slope of 1 and passes through y axis at -2 (y intercept=-2)
equaton is therefor y=1x-2 or y=x-2

compare

line M: y=x-2
line N: y=x-2

they are the same line and lines extend infinitely so therefor there are infinite number of solutions
