Final answer:
Two sets of parametric equations for the given rectangular equation are [x = t, y = 9t - 8] and [x = t + 1, y = 9(t + 1) - 8], providing a representation of the same line with different parameter values.
Step-by-step explanation:
To find two different sets of parametric equations for the rectangular equation y = 9x − 8, we can express x and y in terms of a parameter t. A simple approach is to let x = t, which naturally leads to y = 9t - 8, hereby giving us one set of parametric equations. Another approach is to manipulate the parameter, for instance, by setting x = t + 1, which changes y accordingly to y = 9(t + 1) - 8.
So the two sets of parametric equations could be:
- [x = t, y = 9t - 8]
- [x = t + 1, y = 9(t + 1) - 8]
Both sets represent the same line in the Cartesian plane, but they trace the line with different parameter values for t.
