1. Which ordered pair is a solution of the equation y = x - 4?

[ Option A ]

(2,6)

y = x - 4

6 = 2 - 4

6 = -2 ❎

[ Option B]

(6,2)

y = x - 4

2 = 6 - 4

2 = 2 ✔️

[Option C ]

(-2,6)

y = x - 4

6 = -2 - 4

6 = -6 ❎

[ Option D ]

(-6,2)

y = x - 4

2 = -6 - 4

3 = -10 ❎

2. Which value is a solution of the equation 3 - 2x = -5?

A. 2

B. 4✔️

C. -2

D. 1/5

Step by step explanation :

3 - 2x = -5

3 + 5 = 2x

8 = 2x

8/2 = x

4 = x

3. Which ordered pair is a solution of the equation y = 5x?

A. (-2,10)

B. (-5,25)

C. (-3,15)

D. (-2,-10)✔️

Step by step explanation :

y = 5x

y/x = 5

(-10)/(-2) = 5

4. Which ordered pair is a solution of the equation y = -9x + 4?

A. (10,-86)

y = -9x + 4

-86 = -9(10) + 4

-86 = -90 + 4

-86 = -86 ✔️

B. (-4,-58)

y = -9x + 4

-58 = -9(-4) + 4

-58 = 36 + 4

-58 = 40 ❎

C. (6,-41)

y = -9x + 4

-41 = -9(6) + 4

-41 = -54 + 4

-41 = -50 ❎

D. (-6,57)

y = -9x + 4

-57 = -9(-6) + 4

-57 = 54 + 4

-57 = 58❎
