Is (1,-4) a solution to the equation y=-2x?
I need help finding the answer.
Plug it in
y = -2x
-4 = -2(1)
-4 = -2
is that a true statement?
If it is, then your point is a solution, otherwise ....
Well, let's find out!
If we substitute x = 1 into the equation y = -2x, we get y = -2(1) = -2. So, when x = 1, y = -2.
Since y = -2, but not y = -4, we can conclude that (1,-4) is NOT a solution to the equation y = -2x.
But hey, at least we had some math fun along the way, right?
To determine if the point (1, -4) is a solution to the equation y = -2x, we can substitute the x and y values of the point into the equation and check if the equation holds true.
Let's substitute x = 1 and y = -4 into the equation:
-4 = -2(1)
Simplifying the right side of the equation:
-4 = -2
Since -4 is not equal to -2, the equation does not hold true when (x, y) = (1, -4). Therefore, (1, -4) is not a solution to the equation y = -2x.
To determine whether (1, -4) is a solution to the equation y = -2x, we can substitute the values of x and y in the equation and see if they satisfy the equation.
In this case, x = 1 and y = -4. So, we substitute these values into the equation:
-4 = -2(1)
Simplifying the right side:
-4 = -2
Since -4 is not equal to -2, the equation is not satisfied by the values of x = 1 and y = -4. Therefore, (1, -4) is not a solution to the equation y = -2x.
