Question

Which ordered pair is a solution

y=-3x – 4.
Choose 1 answer:
A.) Only (-2,4)
B.) Only (-3,5)
C.) Both (-2,4) and (-3,5)
D.) Neither

Answer 1

B) Only (-3, 5)

Explanation:

Slot in the options into the equation

(-2, 4),

Compare with (x, y)

x = -2, y =4

y =-3x - 4

4 =( -3 * -2 ) - 4

4 = 6 - 4

This is not true hence, option A is wrong

Using (-3, 5)

x = -3, y= 5

5 = (-3*-3) - 4

5 = 9 - 4

This is correct hence, option B is correct

Option c is wrong because (-2,4) is not a solution to the equation

Option D is wrong because option B is correct
