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.
tell whether the equation has the ordered pair as a solution.
y=7x;(-1,7)
