Question

Denzel wants to walk to the store from his house but he is not sure how far away it is.Find the distance between his house (-6, 8) and the store (7, -1). Each unit is equal toone mile. Round your answer to the nearest mile. Also, describe how you found youranswer.

Answer 1

Remember that

The formula to calculate the distance between two points is given by

`d=√((y_2-y_1)^2+(x_2-x_1)^2)`

we have the points

house (-6, 8) and the store (7, -1)

substitute the given coordinates in the formula above

`\begin{gathered} d=√((-1-8)^2+(7+6)^2) \\ d=√(81+169) \\ d=√(250) \\ d=16\text{ miles} \end{gathered}`

therefore

The answer is 16 miles
