Question

1 - which ordered pair is the solution of the equation y=x-4

A - (2,6)
B - (6,2)
C - (-2,6)
D - (-6,2)

2 - which ordered pair is a solution of the equation y=5x

A - (-2,10)
B - (-5,25)
C - (-3,15)
D - (-2,-10)

3 - which ordered pair is a solution of the inequality y = -9x + 4

A - (10,-86)
B - (-4,-58)
C - (6,-41)
D - (-6,57)

Answer 1

1. B - (6,2)
6 = x
6 - 4 = y = 2

2. D - (-2,-10)
-2 = x
-2 × 5 = y =-10

3. A - (10,-86)
10 = x
10 × -9 = -90
-90 + 4 = -86
