Question

using the distance formula find the distance between the two points. round your result to two decimal places. 38. p(8, -4), q(1, -4)

Explanation:

Step1: Recall distance formula

The distance formula between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$. Here, $x_1 = 8,y_1=-4,x_2 = 1,y_2=-4$.

Step2: Substitute values

$d=\sqrt{(1 - 8)^2+(-4-(-4))^2}=\sqrt{(-7)^2+(0)^2}=\sqrt{49 + 0}$.

Step3: Calculate result

$d=\sqrt{49}=7.00$

Answer:

$7.00$
