Look at the point P on the number line.Which number lines have a point that is equal to pointP? Check all that apply.р
Viktor [21]

In the given Number line the differece between each interval is 10

and the Point P is at -40

Since,

In the graph

A)

the first is -60, then it will be -50 So,

The point P is at -50

Thus the the number line have the same point

B) In the given number line the first point is -60

then -50, -40 and then -30

So, the point is at -30

This number line is not equal to the given number line

C) In the given number line the first point is at -60

and there are three interval so, the the three interval have the values 20

So, the second point will be -40

and the third will be -20

So, the point is at -40

The number line is equal to given number line

D) In the given number line, the interval are divided by 4 parts so

the each interval of the 15 units

the first is at -60

second is at -45
