Question

What is the distance between points (4, −7) and (−5, 9)? Round to the nearest tenth of a unit.

--- units

Answer 1

Plot the points first. Find the horizontal and vertical displacement from one point to another and then use the Pythagorean Formula.

Answer 2

\(\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({\color{red}{ 4}}\quad ,&{\color{blue}{ -7}})\quad
% (c,d)
&({\color{red}{ -5}}\quad ,&{\color{blue}{ 9}})
\end{array}\qquad
% distance value
d = \sqrt{({\color{red}{ x_2}}-{\color{red}{ x_1}})^2 + ({\color{blue}{ y_2}}-{\color{blue}{ y_1}})^2}\)

Answer 3

the answer is rounded to about 18.36

Answer 4

and no u dont u tht @jdoe0001

Answer 5

u use the process of Pythagorean therom

Answer 6

@kandy=D would it be 18.4? due to rounding the 6 to the nearest tenth
