Answer: D
Step-by-step explanation:
No two coordinates can have to same input(x) and different outputs(y)
Answer:
9.06 × 10
Step-by-step explanation:
Without any calculations it's evident it can't be neither B (both numbers are even, so they're divisible by 2) nor C (the numbers end in 0 and 5, so they're divisible by 5).
A.

Both numbers have a factor of 3, so they're not relatively prime.
That means it must be D. But, let's check it.

Indeed, those two numbers are relatively prime.
The equation of a line can be written as:

Where (xo, yo)=(3, 1)


The equation of the line is:
