Which number line can be used to find the distance between (4, –1) and (8, –1)? A number line going from negative 2 to positive 8 in increments of 1. Points are at 4 and 8. A number line going from negative 2 to positive 8 in increments of 1. Points are at negative 1 and positive 4. A number line going from negative 2 to positive 8 in increments of 1. Points are at negative 1 and positive 8. A number line going from negative 8 to positive 2 in increments of 1. Points are at negative 8 and negative 4.

A number line going from negative 2 to positive 8 in increments of 1. Points are at 4 and 8.

Step-by-step explanation:

A number line is a straight line with numbers placed at regular intervals. Since the distance between two points  (4, –1) and (8, –1) is needed to be found, they have the same y coordinate therefore they lie on the same line. To determine the distance between the two points a number line going from - 2 to + 8 in increments of 1. Since the x coordinates of the two points are 4 and 8, on the number line points 4 and 8 are marked.

From the number line, the distance between the two points = 8 - 4 = 4 units

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
