Question

Graph the solution of the inequality 3x+7>13

Answer 1

`3x+7 > 13\implies 3x>6\implies x > \cfrac{6}{3}\implies x > 2`

Check the picture below, notice the line at x = 2 is dashed, or namely it doesn't include that value, because "x greater than 2" means 2.1, 2.2, 2.0001, 2.0000001 anything above but never 2.
