Try each ordered pair in the equation.
y = 7x - 3
Try (1, 4)
1 is x and 4 is y
y = 7x - 3
4 = 7(1) - 3
4 = 7 - 3
4 = 4 This is a true statement, so ordered pair (1, 4) is a solution.
Try (-1, -4)
y = 7x - 3
-4 = 7(-1) - 3
-4 = -7 - 3
-4 = -10 This is a false statement, so the ordered pair (-1, -4) is not a solution.
Answer: (1, 4) is a solution.
