Final answer:
The (x, y) pair for the value of parameter t = 4 is found by substituting t into the given equations. Assuming a typo in the original question, and using the correct equation y = 9 + 3x, we calculate the values to find the pair (8, 33).
Step-by-step explanation:
To find the (x, y) pair for the value of the parameter t, we must first identify the given equations and the value of t. In this case, we have x = 2t and a slightly unclear y equation, which appears to be y = 2 + 9 for t = 4, but judging from the context provided, it may be a typo or an omission. Assuming the intended equation for y is y = 9 + 3x (which makes more sense in this context), we would substitute the value of t into both equations to solve for x and y.
The first step is to substitute t = 4 into the x equation:
x = 2 × 4
x = 8
With the value for x determined, we then substitute x into the y equation:
y = 9 + 3 × 8
y = 9 + 24
y = 33
Thus, the (x, y) pair for t = 4 is (8, 33).
