The ordered pairs that satisfy the equation y = -9x are E(-2, 18) and C(0, 0).
To determine which of the ordered pairs satisfy the equation y = -9x, we can substitute the x-value of each ordered pair into the equation and evaluate. If the resulting y-value matches the y-value in the ordered pair, then the ordered pair satisfies the equation.
Ordered Pair 1: (1, 9)
Substituting x = 1 into the equation:
y = -9(1)
y = -9
Since -9 ≠ 9, the ordered pair (1, 9) does NOT satisfy the equation.
Ordered Pair 2: (-2, 18)
Substituting x = -2 into the equation:
y = -9(-2)
y = 18
Since 18 = 18, the ordered pair (-2, 18) satisfies the equation.
Ordered Pair 3: (0, 0)
Substituting x = 0 into the equation:
y = -9(0)
y = 0
Since 0 = 0, the ordered pair (0, 0) satisfies the equation.
Therefore, the ordered pairs that satisfy the equation y = -9x are E(-2, 18) and C(0, 0).
