Question

Write an equation involving absolute value for each graph.

Step-by-Step Solution

Answer

The absolute value equation will be $\left|x-1\right|=4$.

Step-1. Define absolute value equation.

For any real numbers a and b, if $\left|a\right|=b$ and $b\ge 0$, then $a=b$ or $a=-b$.

Step-2. Find the mid-point of points -3 and 5.

To find the point midway between two points -3 and 5, add the two values and divide by 2.

$\begin{array}{c}\text{Midpoint}=\frac{-3+5}{2}\\ =\frac{2}{2}\\ =1\end{array}$

Step-3. Write the equation.

Since, the midpoint of -3 and 5 is 1, that is, the distance from -3 to 1 is 4 units and the distance from 1 to 5 is also 4 units.

 

So, the absolute value equation will be: $\left|x-1\right|=4$.
