The correct answer is -9/5
Hope this helped :)

Answer 2

Answer:

-9/5

Step-by-step explanation:

The usual formula of a line is  y = mx + b, where m is the slope and b is the y-intercept.

Knowing this, we need to convert our equation into that form to find our m.

9x + 5y = 1

We subtract 9x on both sides:

9x + 5y - 9x = -9x + 1

5y = -9x + 1

Now we multiply by 1/5 on both sides:

5y * 1/5 = (-9x + 1) * 1/5

y = -9/5x + 1/5

Therefore, the slope of the line is m = -9/5
