tell whether the equation has the ordered pair as a solution.
y=7x;(-1,7)
To determine whether the ordered pair (-1,7) is a solution to the equation y=7x, we can substitute the values of x and y into the equation.
Given that x = -1 and y = 7, we substitute these values into the equation:
7 = 7(-1)
The right-hand side simplifies to:
7 = -7
Since 7 does not equal -7, the equation does not hold true for the given ordered pair (-1,7). Therefore, (-1,7) is not a solution to the equation y=7x.
To determine whether the equation y = 7x has the ordered pair (-1,7) as a solution, let's substitute the values of x and y from the ordered pair into the equation and see if it holds true.
Substituting x = -1 and y = 7 into the equation, we have:
7 = 7(-1)
Simplifying the right side of the equation:
7 = -7
Since 7 is not equal to -7, the equation y = 7x does not have the ordered pair (-1,7) as a solution.
To determine if the equation has the ordered pair (-1, 7) as a solution, we can substitute the values of x and y into the equation and see if the equation holds true.
The equation is y = 7x.
To do this substitution, we replace the variable x with the x-coordinate (-1) and the variable y with the y-coordinate (7) of the ordered pair (-1, 7).
So, substituting into the equation, we have:
7 = 7*(-1)
Now, we simplify both sides:
7 = -7
Since -7 is not equal to 7, our equation did not hold true when we substituted the values. Therefore, (-1, 7) is not a solution to the equation y = 7x.
