Question

a) In the coordinate plane, what is the horizontal axis called
and what is the vertical axis called?
(b) To graph an ordered pair of numbers 1x, y2 , you need the
coordinate plane. For the point 12, 32 , which is the
x-coordinate and which is the y-coordinate?
(c) For an equation in the variables x and y, how do you
determine whether a given point is on the graph? Is the
point 15, 32 on the graph of the equation y  2x  1?
