Ordered pairs are pairs of values of x and y that satisfy a given equation or a function. It is presented in the order x,y and eclosed in parentheses, as in (x,y).
For the equation y=5x-8, the value of x=0 gives the value of y=-8, so (0,-8) is an ordered pair.
This ordered pair happens to be the y-intercept, i.e. the point where the line intersects the y-axis, characterized by x=0.
To get other (arbitrary) ordered pairs, substitute different values of x into the equation, and put the pair of x and y values in parentheses.
Thank you for your help. Your explanation has been one of the clearest I have heard!
You're very welcome!
Complete the following ordered pairs for the equation. 4x+5y=-22(_, -2) (2, _)(7, _)
