Becky draws a triange with vertices
a (6,7) b(9,3) and c(4,-2) on a coordinate
grid. she reflects the triangle across
the line y = 4 to get a a'b'c'. she then reflects the image across the line x=3 to get a”b”c”

after simplifying it i got: -36.25 as my answer. hope that !

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
