Is (1,−7) a solution to the equation y=x−8?
To determine if (1,-7) is a solution to the equation y = x - 8, we substitute x = 1 and y = -7 into the equation and check if the equation holds true.
Substituting the values of x and y into the equation, we get:
-7 = 1 - 8
Simplifying the right side of the equation:
-7 = -7
Since both sides of the equation are equal, we can conclude that (1,-7) is indeed a solution to the equation y = x - 8.
To check if (1, -7) is a solution to the equation y = x - 8, we need to substitute the values of x and y into the equation and see if both sides are equal.
So, let's substitute x = 1 and y = -7 into the equation:
-7 = 1 - 8
Now let's simplify the right side of the equation:
-7 = -7
Since the left side and the right side of the equation are equal, we can conclude that (1, -7) is indeed a solution to the equation y = x - 8.
