Question

All of the following ordered pairs satisfy the function rule y=-3x+2 except

(1, -1)
(4,-10)
(-2,8)
(-3, 12)

Answer 1

The ordered pair (-3, 12) DOES NOT satisfy the equation.

Explanation:

Given the function

`y=-3x+2`

Let us substitute all the values to check which points satisfy the function.

FOR (1, -1)

y = -3x+2

substitute x = 1, y = -1

-1 = -3(1) + 2

-1 = -3+2

-1 = -1

TRUE!

Thus, the ordered pair (1, -1) satisfies the equation.

FOR (4, -10)

y = -3x+2

substitute x = 4, y = -10

-10 = -3(4) + 2

-10 = -12+2

-10 = -10

TRUE!

Thus, the ordered pair (4, -10) satisfies the equation.

FOR (-2, 8)

y = -3x+2

substitute x = -2, y = 8

8 = -3(-2) + 2

8 = 6 + 2

8 = 8

TRUE!

Thus, the ordered pair (-2, 8) satisfies the equation.

FOR (-3, 12)

y = -3x+2

substitute x = -3, y = 12

12 = -3(-3) + 2

12 = 9+2

12 = 11

L.H.S ≠ R.H.S

FALSE!

Thus, the ordered pair (-3, 12) DOES NOT satisfy the equation.

Therefore, the ordered pair (-3, 12) DOES NOT satisfy the equation.
