Answer:
C
Step-by-step explanation:
Each input value can have only one output value for it to be a function. In other words, there should only be one y value for each x value. The only option that satisfies this is C.

Answer:
Part A: t = 2 and y = 7
Part B: Point of intersection is (2,7)
Step-by-step explanation:
Part A: We are given the pair of equations shown below:
y = 8t - 9 ......... (1)
y = 4t - 1 ............ (2)
We can solve those equations by the elimination method.
We have from [equation (1) - equation (2)], 0 = 4t - 8
⇒ t = 2
Therefore, from equation (2), we get y = 4 ×2 - 1 = 7
Hence, t = 2 and y = 7 is the solution of the given pair of equations.
Part B: As equation (1) and equation (2) are two straight lines, so their solution gives the point of intersection of those two lines on the graph.
Therefore, if we plot t along the X-axis and y along the Y-axis then the point of intersection will be (2,7) point. (Answer)
