tell whether the given ordered pair is a solution of the equation
y=9-2x;(-2,5)
Help i kinda don't understand
if it is, then
y=9-2x or
y=9-2*-2=0+13
Hmmm, not a solution
Thank you!!!
To determine if a given ordered pair is a solution of an equation, you need to substitute the values of the ordered pair into the equation and see if the equation is true.
In this case, you have the equation y = 9 - 2x and the ordered pair (-2,5).
Let's substitute the values from the ordered pair into the equation:
x = -2
y = 5
Replace x with -2 and y with 5 in the equation:
5 = 9 - 2(-2)
Now, simplify the equation by performing the operations:
5 = 9 + 4
Continue simplifying:
5 = 13
Since 5 does not equal 13, the equation is not true with the given ordered pair (-2,5). Therefore, the ordered pair (-2,5) is not a solution of the equation y = 9 - 2x.
