Tell whether the ordered pair is a solution of the equation. y = x + 4; (2, 4)

Sagot :

To determine if the ordered pair (2,4) is a solution of the equation y=x+4, you have to replace the equation with the x-coordinate of the given ordered pair and calculate the corresponding value of y. Then you have to compare both y-values

The coordinates of the ordered pair are:

x=2

y=4

Replace the equation with x=2 and calculate the value of y:

[tex]\begin{gathered} y=x+4 \\ y=2+4 \\ y=6 \end{gathered}[/tex]

The calculated y-coordinate is y=6, but the given y-coordinate is y=4, this indicates that the ordered pair (2,4) is not a solution of the equation.
