Find an ordered pair , x y that is a solution to the equation. 5x-y=9

(1, -4)

Step-by-step explanation:

In order to find a solution to a linear equation, we can substitute any value for one variable, simplify the equation, and find the value of the other variable to find a solution that is an ordered pair.  

Since any value for either variable will do, we can choose something simple, such as 1. I chose to substitute 1 for x into the equation, as seen below.  

Now, all I need to do is solve and isolate y:

So, with this linear equation, when x equals 1, y equals -4. Thus, a solution to the equation is (1, -4).

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
