• AX + BY + C = 0 • AX + BY + C = DX + EY + F
DX + EY + F = 0 GX + HY + I = JX + KY + L
• AX + BY = C • AX + BY = C
Y = DX + E DX + EY + F = 0
• AX + BY = C • AX + BY + C = 0
DX + EY + F = GX + HY + I Y = DX + E
• AX + BY + C = DX + EY + F • AX + BY + C = 0
Y = GX + H DX + EY + F = GX + HY + I
Pressing 6(EXCH) reverses the left side and right side elements of the expression.
