Question

On the coordinate grid of a map, Josie's house is located at (2,7). Her school is located at (-5,5). If each map unit equals one mile, what is the approximate distance from her house to school? Help me out i'm so confused >.

Answer 1

To find the distance you would use the distance formula which is:
$d = \sqrt{(x2-x1)^{2}+(y2-y1)^{2}} = \sqrt{(2-(-5))^{2}+(7-5)^{2}}$

This equals:
$d = \sqrt{(7)^{2}+(2)^2} = \sqrt{49+4} = \sqrt{53} = 7.2801$

Answer 2

Answer:

The answer is C. 7.28
