Question

What is the distance between the points (8, 3) and (8, –6)?



A.
3 units


B.
8 units


C.
9 units


D.
17 units

Answer 1

Are you able to plot the two points?

Answer 2

\(\large\color{blue}{ \rm d=\sqrt{(y_1-y_2)^2+(x_1-x_2)^2} }\)

Answer 3

Well, you can use the dystance formula, but there is something you should notice about those points that makes it even easier.

Answer 4

\(\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ 8}}\quad ,&{\color{blue}{ 3}})\quad &({\color{red}{ 8}}\quad ,&{\color{blue}{ -6}})
\end{array}\qquad
d = \sqrt{({\color{red}{ x_2}}-{\color{red}{ x_1}})^2 + ({\color{blue}{ y_2}}-{\color{blue}{ y_1}})^2}\)

Answer 5

I don't get it

Answer 6

Here's what you would get if you plotted the two points on a xy grid

Answer 7

What do you notice about the points?

Answer 8

i get it now

Answer 9
