the equation is 1 / (x-5)

there will be a vertical asymptote at x = 5.

as x approaches 5 from the left, the value of y gets more and more negative.

as x approaches 5 from the right, the value of y gets more and more positive.

you want to know the value of y as x approaches from the left.

the value of y gets more and more negative as x approaches 5 from the left, which makes the value of y approaching negative infinity.

that would make your solution as:

minus infinity; x = 5

here's my graph.

without the graph, you would take values of x very close to 5 from the left and values of x very close to 5 from the right and see which way they are going.

for example:

1 / (4.9999 - 5) = -10000
1 / (4.99999999 - 5) = -100000000

it's getting more and more negative.

1 / (5.0001 - 5) = 1000
1 / (5.00000001 - 5) = 100000000

it's getting more and more positive.
