Answer: 9) The ordered pair is not a solution. 10) Yes the ordered pair is a solution.
Explanation:
9) y = x + 11 (4,13) so we now the 4 is the x and 13 is y so plot it into the equation.
13= 4 + 11
13 ≠15 which means is not a solution because 13 does not equal to 15.
10) y = 6x (8,48) the same applies to this
48 = 6(8)
48 = 48 which means (8,48) is a solution to the equation because 48 does equal 48.
