Question 218922: find the distance between points at (6, -3) and (-1, 4)
Answer by RAY100(1637)   (Show Source):
You can put this solution on YOUR website! the distance formula is ,,,,d= sqrt{y2-y1)^2 + (x2-x1)^2 }
.
for (6,-30,,,,(-1,4)
.
d= sqrt( -30 -4)^2 + (6-(-1) )^2 }
.
d= sqrt { (-34)^2 + (7)^2 }
.
d=sqrt { 1156 +49 }
.
d=sqrt { 1205)
.
d=34.713
.
.
a rough sketch always helps clarify.
.
the change in y = 34,,,and the change in x= 7,,,c^2 = a^2+b^2,, d^2=34^2+7^2,,,d=34.713,,,ok
