First, you'd need to transform the equation into y = mx + b
To do this, set up the original equation and solve for y.
x + 5 y = -5
Subtract x from both sides.
5y = -5 - x
Now, divide by 5 into both sides to leave y on one side.
y = -1 -x/5
With this new equation, just shift the numbers on the right of y to create a y = mx + b equation
y = -x/5 - 1
Therefore, you're y intercept is -1 and you're slope is -x/5.
Hope this helps!
