Based on the chart on the left, you can see there are 2 dragonflies with the lengths of 3 1/4 inches. Therefore, 2 marks should be made over the 3 1/4 inches spot on the line plot.
Hope this helps

Answer:
$3
Step-by-step explanation:
17 - 5 = 12 divided by 4 = 3
Direct variation: y=kx where k is some number thats not 0
that means if x is 2, y is 2k. if x is 1, y is k. if x is 0, y is 0.
notice: no matter what k is, when you put 0 in for x, y will always be 0. that means that a direct variation always goes through the origin, a.k.a. (0,0).
do all lines go through the origin? nah. a line is y=mx+b, where m and b are some numbers. a line is only a direct variation if b is 0. this makes sense because if b is 0, then the y-intercept is 0, so the line goes through the origin.
in conclusion, no, not all linear relationships are direct varations, but all direct variations are linear relationships.
Answer:
Two quantities x and y are said to be proportional if ratio yx for related pairs of x and y is equivalent.
Step-by-step explanation:
Two quantities x and y are said to be proportional if ratio
for related pairs of
and y is equivalent.
The symbol ∝ is used to denote the proportionality. For example, if
is proportional to y, then it is represented as
∝y and if
is inversely proportional to y, then it is represented as
∝ 1/y
