What are the coordinates of the origin?
Think about point zero on both axes.
Plot the point (2, 3) on a graph paper.
Remember to start at the origin.
What is the distance formula for points P(x1, y1) and Q(x2, y2)?
Recall the formula involving squares.
True or False: The coordinates of the point (2, 3) indicate it is 2 units from the x-axis and 3 units from the y-axis.
Think about how each coordinate corresponds.
Given points A(1, 2), B(3, 1), and C(-1, -1) determine if they are collinear.
Use the distance formula.
Find a point on the y-axis equidistant from A(3, 4) and B(7, 8).
You'll use the distance formula to set two equations equal.
