Hello, can you please help? I don't understand how to solve this very well.
Question: Which ordered pair is the solution of the equation y = 3x?
Answer Choices:
A: (-2,-9)
B: (-8,-18)
C: (-8,-3)
D: (-10,-30)
To all who help you have my thanks!! :)))
it says y = 3x
look at your ordered pairs.
Can you see one or more where the y value is 3 times its x value???
Remember the x is the first number, the y is the 2nd number.
Yes
ok thank you very much
@sunset love hello hru? ^-^
Of course! I'll be glad to help you solve the equation and determine which ordered pair is a solution.
The given equation is y = 3x. To find out which ordered pair satisfies this equation, you need to substitute the x and y values from each answer choice into the equation and check if both sides of the equation are equal.
Let's consider each answer choice:
A: (-2, -9)
To check if this is a solution, substitute x = -2 and y = -9 into the equation:
-9 = 3(-2)
-9 = -6
Since -9 is not equal to -6, (-2, -9) is not a solution of the equation y = 3x.
B: (-8, -18)
Substituting x = -8 and y = -18 into the equation:
-18 = 3(-8)
-18 = -24
Since -18 is not equal to -24, (-8, -18) is not a solution of the equation y = 3x.
C: (-8, -3)
Substituting x = -8 and y = -3 into the equation:
-3 = 3(-8)
-3 = -24
Again, -3 is not equal to -24, so (-8, -3) is not a solution of the equation y = 3x.
D: (-10, -30)
Substituting x = -10 and y = -30 into the equation:
-30 = 3(-10)
-30 = -30
Here, -30 is equal to -30, so (-10, -30) is a solution of the equation y = 3x.
Therefore, the correct answer is D: (-10, -30) is the solution of the equation y = 3x.
