Question

A triangle is graphed in the coordinate plane. The vertices of the triangle have coordinates (-5, 1), (1, 1), and (1, -7). What is the perimeter of the triangle?

Answer 1

What is the length of a line going from (-5,1) to (1,1)?

Answer 2

do u know distance formula?

Answer 3

no

Answer 4

Distance between two points=Sqr root [(y2-y1)^2 +(x2-x1)^2]
Using this find out all distances between vertices. ADD them to get the perimeter. try.
