Question

find the distance between the points (1, 7) and (9, 7). round decimals to the nearest tenth. units save answer

Explanation:

Step1: Identify 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, $x_1 = 1,y_1 = 7,x_2=9,y_2 = 7$.

Step2: Substitute values

Substitute the values into the formula: $d=\sqrt{(9 - 1)^2+(7 - 7)^2}=\sqrt{8^2+0^2}$.

Step3: Calculate

$\sqrt{8^2+0^2}=\sqrt{64 + 0}=\sqrt{64}=8$.

Answer:

8
