Answer: Hello mate!
we have the equation y = –9x + 4 and we want to find ordered a pair that is a solution of the equation. Where a pair has the form (x, y)
First, you need to know that there are infinite ordered pairs that are a solution of this equation, if you want to find them, you need to replace the value of x (or the value of y) with a number, and solve the equation:
suppose x = 1
then y = -9*1 + 4 = -9 + 4 = 5
then the pair (1,5) is a solution of the equation.
The general form of the pairs is (x,y), then the pairs that are a solution for this equation are the pairs of the form (x, y(x)) = (x, -9x + 4)
