Tell whether the ordered pair is a solution of the equation. Just substitute the given x and y to see if the equation “works”. Write “solution” if it works and “not solution” if it doesn’t.
y=4x + 2; (2,10)
2x + y = 5; (7, 5)
For the equation y=4x + 2, substitute x=2 and y=10:
10 = 4(2) + 2
10 = 8 + 2
10 = 10
Since the equation is true when we substitute x=2 and y=10, the ordered pair (2,10) is a solution.
For the equation 2x + y = 5, substitute x=7 and y=5:
2(7) + 5 = 5
14 + 5 = 5
19 = 5
Since the equation is not true when we substitute x=7 and y=5, the ordered pair (7,5) is not a solution.
