<h3>1. Which ordered pair is a solution of the equation y = x - 4?</h3>
[ 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 ❎
<h3>2. Which value is a solution of the equation 3 - 2x = -5?</h3>
A. 2
B. 4✔️
C. -2
D. 1/5
<u>Step by step explanation :</u>
3 - 2x = -5
3 + 5 = 2x
8 = 2x
8/2 = x
<u>4 = </u><u>x</u>
<h3>3. Which ordered pair is a solution of the equation y = 5x?</h3>
A. (-2,10)
B. (-5,25)
C. (-3,15)
D. (-2,-10)✔️
<u>Step by step explanation :</u>
y = 5x
y/x = 5
(-10)/(-2) = 5
<h3>4. Which ordered pair is a solution of the equation y = -9x + 4?</h3>
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❎
