Question

Plot all points that are a distance of 7 units from 4. What are their values?

Answer 1

Distance is the number of units between points.

The distance that are 7 units from 4 are: 11 and -3

A distance of 7 units from 4 means:

$x - 7 = 4$  or $x + 7 =4$

Where:

x is the required distance

Solve for x in both equations.

$x - 7 = 4$

$x = 7 + 4$

$x = 11$

$x + 7 =4$

$x =4 - 7$

$x =- 3$

So, the distance that are 7 units from 4 are: 11 and -3
