Question

How many units long is a line segment whose endpoints have coordinates (-3,7) and (2,-5)?

Answer 1

i think its 13

Explanation:

i just plotted the points on a coordinate plane and counted it out its was around 12.8 so i rounded it and its was 13

Answer 2

D = 13 units

Explanation:

Using Distance Formula to find the length.

Distance Formula =
`√((x2-x1)^2+(y2-y1)^2)`

D =
`√((2+3)^2+(-5-7)^2)`

D =
`√((5)^2+(-12)^2)`

D =
`√(25+144)`

D =
`√(169)`

D = 13 units
