When you multiply or divide each term of an inequality by a negative number, you must remember to
reverse
the symbol of inequality.
If the inequality in slope-intercept form uses the > or < symbols, the boundary between points that are in the solution area and points that are not is a(n)
line. If the inequality in slope-intercept form uses the ≥ or ≤ symbols, the boundary between points that are in the solution area and points that are not is a(n)
line.
If the inequality in slope-intercept form uses the
symbols, the solution area will be a shaded area above the line. If the inequality in slope-intercept uses the
symbols, the solution area will be a shaded area below the line.
