Answer:
a and b
Explanation:
to determine which ordered pairs are solutions to the equation
y = - 2x + 6
substitute the x- coordinate into the equation and if the value obtained is equal to the y- coordinate , then it is a solution.
a (0, 6 )
y = - 2(0) + 6 = 0 + 6 = 6 ← solution
b (1, 4 )
y = - 2(1) + 6 = - 2 + 6 = 4 ← solution
c (- 2, - 2 )
y = - 2(- 2) + 6 = 4 + 6 = 10 ≠ - 2 ← not a solution
the ordered pairs a and b are solutions of the equation
