Which of the following ordered pairs is a solution of the equation y = -4x². Can someone help me solve it. Could you guys also explain why that answer is.
Here are the options/Answers:
(-2,16)
(1, -8)
(0,-4)
(2,-16
your wrong..
To determine whether the given ordered pairs are solutions to the equation y = -4x², we need to substitute the x and y values from each pair into the equation and see if the equation holds true.
Let's start with the first option, (-2, 16):
To check if this is a solution, substitute x=-2 and y=16 into the equation:
16 = -4*(-2)²
16 = -4*(4)
16 = -16
The equation does not hold true, so (-2, 16) is not a solution.
Moving on to the second option, (1, -8):
Substitute x=1 and y=-8 into the equation:
-8 = -4*(1)²
-8 = -4*(1)
-8 = -4
Again, the equation does not hold true, so (1, -8) is not a solution.
Next, let's try the third option, (0, -4):
Substitute x=0 and y=-4 into the equation:
-4 = -4*(0)²
-4 = -4
This time, the equation holds true, so (0, -4) is a solution.
Lastly, let's examine the fourth option, (2, -16):
Substitute x=2 and y=-16 into the equation:
-16 = -4*(2)²
-16 = -4*(4)
-16 = -16
Once again, the equation holds true, so (2, -16) is a solution.
In summary, the only ordered pairs that are solutions to the equation y = -4x² are (0, -4) and (2, -16).
plug in the x and y values for each pair , and see which one works
... makes the equation true
