Objective
To use tables, equations, and graphs to describe relationships
In the Solve It, you may have described the pattern using words. You can also use an equation or a graph to describe a pattern.
Essential Understanding Sometimes the value of one quantity can be found if you know the value of another. You can represent the relationship between the quantities in different ways, including tables, equations, and graphs.
You can use an equation with two variables to represent the relationship between two varying quantities. A solution of an equation with two variables x and y is any ordered pair (x, y) that makes the equation true.
Is (3, 10) a solution of the equation y = 4x?
How can you tell whether an ordered pair is a solution?
Replace x with the first value in the ordered pair and y with the second value in the ordered pair. Is the resulting equation true?
