Who are these "students", who are not able to solve such a simple problem on their own ?

------------


Apply the distance formula


    d = sqrt%28%28x%5B2%5D-x%5B1%5D%29%5E2+%2B+%28y%5B2%5D-y%5B1%5D%29%5E2%29.


In your case  x%5B1%5D = -4,  y%5B1%5D = 2,  x%5B2%5D = 146,    y%5B2%5D = 52. 


Learn this formula and use it.   //   It is written in any textbook for your class.

And  NEVER  come again to this forum with such question/questions.

It is a  SHAME  to do it . . .


Making calculations is the students' honor duty and a privilege !

Hi,
What is the length, to the nearest tenth, of the line segment joining the points (-4, 2) and (146, 52)
D = +sqrt+%28+%28x%5B1%5D-x%5B2%5D%29%5E2%2B+%28y%5B1%5D-y%5B2%5D%29%5E2+%29+
L = +sqrt+%28+%28-150%29%5E2%2B+%28-50%29%5E2+%29+ = 158.1 to the nearest tenth
A Calculator You are comfortable using is a must.
Myself use a Casio fx-115 ES plus (costs less than $20 to my knowledge)
Wish You the Best in your Studies.
