Question

The end points of wx are w (-5,-1) and x (2,6) What is the length of wx

Answer 1

Answer:

9.90 units (3 s.f.)

Step-by-step explanation:

distance formula

$= \sqrt{(x1 - x2)^{2} + (y1 - y2)^{2} }$

Length of WX

$= \sqrt{(2 - ( - 5))^{2} + (6 - ( - 1)^{2} } \\ = \sqrt{(2 + 5)^{2} + (6 + 1)^{2} } \\ = \sqrt{7 ^{2} + 7^{2} } \\ = \sqrt{98} \\ = 9.90 \: units \: (3 \: s.f.)$
