Question 218922
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
.
