H) $-3y = 29$
F) $3x + 6y = 0$ $3x + 6y - 3x = 0-3x$ $6y = -3x$ $6y/6 = -3x/6$ $y = -x/2$ This line is not a horizontal line. G) $2x+7 = 0$ $2x + 7 - 7 = 0 - 7$ $2x = -7$ $2x/2 = -7/2$ $x = -3.5$ This is a vertical line (not a horizontal line). H) $-3y = 29$ $-3y/-3 = 29/-3$ $y = -29/3$ This is a horizontal line. I) $x-2y = 4$ $x - 2y -4 +2y = 4 -4 + 2y$ $x - 4 = 2y$ This is not a horizontal line.
