Answer
a) Horizontal Axis: x-axis, Vertical Axis: y-axis
b) The x-coordinate is 2, while the y-coordinate is 3.
c) Plug in the coordinates into the equation, and (5,3) is NOT.
Work Step by Step
a) A basic idea of graphing. The horizontal axis is the x, and the vertical is y.
b) The x-coordinate ALWAYS comes first. Just like how x in the alphabet comes before y. Therefore the x-coordinate is 2, and the y-coordinate is 3.
c) To determine whether a given point is on the graph of an equation, plug it in. If you plug in x however, and it doesn't equal y, the point is NOT on the graph.
