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 a solution” if it doesn’t.
1) y = 4x + 2; (2, 10) 2) 2x + y = 5; (7, 5) 3) y = 6 – x; (–3, 3) 4) x + 8y = 2; (10, –1) 5) y = 6x + 7; (2, 21)
