Question

Which ordered pair is not a point on the graph of y = –5x + 2?

Answer 1

Answer:

Option A. (-1, 6)

Step-by-step explanation:

If a point (x, y) lies on a graph, then the ordered pairs will satisfy the equation graphed.

For point (-1, 6)

y = -5x + 2

6 = (-5)(-1) + 2

6 = -5 + 2

6 = -3 [Not true]

Therefore, (-1, 6) doesn't lie on this graph.

For point (0, 2),

y = -5x + 2

2 = 0 + 2

2 = 2 [True]

Therefore, (0, 1) lies on the graph.

For point (-2, 12),

y = -5x + 2

12 = (-5)(-2) + 2

12 = 12 {True}

Therefore, point (-2, 12) lies on the graph.

For point (2, -8)

y = -5x + 2

-8 = (-5)(2) + 2

-8 = -8 [True}

Therefore, (2, -8) lies on the given graph

Option A. is the answer.
