Question

Which point is on the line y=-2x+ 3?
(-2, -1)
( 3, -3)
(3, 3)
(-3, -9)
please give how you got your answer

Answer 1

Answer: (3, -3)

Step-by-step explanation:

You substitute each point into the function and see if it fits:

(-2, -1) ⇒ -2(-2) + 3 = 4 + 3 = 7 ≠ -1

(3, -3) ⇒ -2(3) + 3 = -6 + 3 = -3

(3, 3) ⇒ -2(3) + 3 = -6 + 3 = -3 ≠ 3

(-3, -9) ⇒ -2(-3) + 3 = 6 + 3 = 9 ≠ -9

Answer 2

(3,-3) I plugged the equation on a graphing calculator the checked for the points
