Question

Find all values of y such that the distance between (7,y) and (-3,8) is 18 Y=

Answer 1

To calculate the distance between 2 points we will use the following equation:

$D=\sqrt[]{(x_2-x_1)^2-(y_2-y_1)^2}$

For this exercise we have the following data:

$\begin{gathered} D=18 \\ x_1=7 \\ x_2=-3 \\ y_1=y \\ y_2=8 \end{gathered}$

We plug the values into the distance equation and solve for the unknown Y
