ANSWER:
x + y = 0
x - y = 0
Step-by-step explanation:
Given the coordinates:
A(-3,3)
B(3,3)
C(3,-3) and
D (-3,-3)
One diagonal is line AC.
Find the slope of AC:
Solpe of AC = -1
Using the slope intercept form, y = mx+b, we have:
y = -1x + b
y = -x + b
The equation for AC:
y = -x
The other diagonal is BD.
find the slope of BD:
Slope of BD = 1
The equation of BD:
y = 1x
y = x
Therefore the equation of both lines in standard form will be:
AC ==> x + y = 0
BD ==> x - y = 0
