What you'll learn
- Explain that the graph of an equation in two variables is the set of ALL ordered pairs (x, y) that make the equation true -- not just "some" or "selected" points
- Verify whether a given point lies on the graph of an equation by substituting its coordinates and checking whether both sides are equal
- Graph equations in two variables by generating a table of values, plotting the points, and connecting them with a smooth curve or line
- Distinguish between the graph of an equation in one variable (a point or set of points on a number line) and the graph of an equation in two variables (a curve in the coordinate plane)
- Recognize that the graph of an equation in two variables can take many shapes -- line, parabola, circle, exponential curve, and others -- all of which are complete visual representations of the equation's solution set
