Final answer:
To determine whether the given ordered pair is a solution of each equation, substitute the values and check if the equations hold true.
Step-by-step explanation:
To determine whether the given ordered pair is a solution of each equation, we substitute the values of x and y into the equation and check if the equation holds true.
Equation 1: 3x + 5 = y
Substituting the values from the ordered pair (1, 8):
3(1) + 5 = 8
3 + 5 = 8
8 = 8
The equation is true, so (1, 8) is a solution.
Equation 2: y = (x - 1.2)(-3)
Substituting the values from the ordered pair (0, 1.2):
1.2 = (0 - 1.2)(-3)
1.2 = (-1.2)(-3)
1.2 = 3.6
The equation is not true, so (0, 1.2) is not a solution.
