Can anyone tell me if the ordered pair (x,y) = (5.8,2.0) is a solution to the equation y = 4x - 21.2
I would appreciate it if someone show me the best way to make this determination.
Hi there.
The first value of the ordered pair is the x value, and the second is the y value. So to complete the ordered pairs in those questions you just need to replace the x in the equation with the value you are given, then solve this to find the y value.
For the first one:
so
So the ordered pair would be
Are you able to do the other ones now?
