How many proportional relationships are shown in the coordinate plane below? Choose 1

A 0

B 1

C 2

D 3

An easy way to determine if a graph shows a proportional relationship is to see if the graph is a straight line.

If the graph results in a straight line, then it is a proportional relationship.

As we can see in this case, all three graphs are straight lines, so D is the correct answer, because there are 3 proportional relationships.

Let me know if this helps!

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
