Hey there!
According to the question, you need to find out the distance from your friend's house to school.
<em>Firstly figure out the coordinate of your school and school. Then use formula of distance.</em>
So, we find the coordinates as (7,7) and (5,0).
So, x 1 = 7 y1= 7
x 2 = 5 y2 = 0
~ Use distance formula.

~ Put all values.

~ Simplify it.



D= 7.280
Therefore, the distance between your friend's house and your school is 7.3 units.
