Which of the following expressions represents the distance between a and b on a number line? Choose all answers that apply:
A
a-bi
B
16 - a
None of the above

A and B

Step-by-step explanation:

The distance between any two points with coordinates a and b respective, can be gotten by finding the absolute value of the difference between the coordinates of the two points on the numberline.

For example, where a and b are coordinates of the two points in the numberline, the expression of their distance can be written in two ways:

|a - b| or |b - a|.

Both expressions will give us the same value.

For example, if a = -6, and b = 7, the distance between -6 and 7 in a numberline can be written as:

|-6 - 7| = |-13| = 13

Or

|7 -(-6)| = |7 + 6| = 13

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
