Question

Does the point (3, 1) satisfy the equation y = 3x?yes or no

Answer 1

We can solve this question if we evaluate the value of x into the function. Then, we have:

x = 3 ---> y = 1. We need to prove this. Then:

`y=3x\Rightarrow x=3\Rightarrow y=3\cdot(3)\Rightarrow y=9`

Therefore, we have that the point (3, 1) does not satisfy this equation since for a value of x = 3, the value for y = 9 (not 1).

Hence the point (3, 1) is NOT a solution for y = 3x (then, the option is No).
