Question 1083687: Indicate the equation of the given line in standard form.
The line containing the diagonal of a square whose vertices are A(-3, 3), B(3, 3), C(3, -3), and D(-3, -3). Find two equations, one for each diagonal.

Diagonal one goes from D to B and has a slope of 1
point slope formula y-y1=m(x-x1), m slope and (x1,y1) coordinate
y-3=1(x-3)
y=x
============
Other diagonal goes from upper left to lower right and has a slope of -1
y-3=-1(x+3)
y=-x
Standard form is x-y=0 for one line and x+y=0 for the other
