Given A(-3,2)B(1,-4) answer the Question
Find The length of line AB. Round to the tenths place if needed.
+129852 Length =
sqrt [ ( subtract x coordinates)^2 + (subtract y coordinates )^2 ] =
[BTW...the order in which the coordinates are subtracted makes no difference ]
sqrt [ ( -3 - 1)^2 + ( - 4 - 2)^2 ] =
sqrt [ (-4)^2 + (-6)^2 ] =
sqrt [ 16 + 36 ] =
sqrt [ 52 ] =
sqrt [ 4 * 13 ] =
sqrt [ 4 ] * sqrt [ 13 ] =
2*sqrt [ 13]
