What is the ordered pair of x-2y equals -4 2x-y equals 1?
This is a simultaneous equation question: x-2y = -4 2x-y = 1 Multiply all terms in the top equation by 2: 2x-4y = -8 2x-y = 1 Subtract the bottom equation from the top equation remembering that a minus minus equals a plus: -3y = -9 Divide both sides of the equation by -3 to find the value of y remembering that a minus divided by a minus equals a plus: y = 3 Substitute the value of y into the original equations to find the value of x: Solution: x = 2 and y = 3

Is this equation a function y equals 3squared plus 2x minus 3 is this a function?
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
What order pair is a solution for y equals 2x minus 1?
Choose any value for "x", replace that in the equation, and calculate the corresponding value for "y".
