I understand the equation to be y = -3x - 2 and the point to be (5,1).

I substitute 1 for each appearance of y and 5 for each appearance of x:

1 = -3(5) - 2 = -15 - 2 = -17, which is not a true statement. Therefore, that is not a solution.

To get a solution, set x=1, and calculate y by substituting this value (1) for x wherever it appears:

y = -3(1) - 2 = -3 - 2 = -5.

Therefore, (-5,1) is a solution. (I suspect that this is what you meant to put in the question.)

There's no fun in playing it safe. Why not try something a little unhinged?
