Respuesta :

The number line that represents the solutions to Ix - 5| = 1 is the number line in the second option.

To solve absolute value equations like |x-5| = 1

We will write that

x - 5 = 1 and x -5 = -1

For the first equation

x - 5 = 1

Add 5 to both sides

x - 5 +5 = 1+5

x = 6

For the second equation

x -5 = -1

Add 5 to both sides as well

x -5 +5 = -1 +5

x = 4

Hence, x = 6 and x = 4

From the image, the second option is dotted (blue) at 4 and 6 on the number line.

Hence, the number line that represents the solutions to Ix - 5| = 1 is the number line in the second option
