5=-10x-10y

What's the slope for this parellel line?

-1

Step-by-step explanation:

Equation of a line:

y = mx + c

m is the slope.

Let's put your equation into the format above by rearranging.

5 = - 10x - 10y

First let's get 10y on it's own.

Move - 10y to the left.

10y + 5 = - 10x

Move 5 to the right.

10y = - 10x - 5

Now divide by 10 to get the values for 1 y.

10y/10 = - 10x/10 = - 5/10

y = - x - 0.5

You slope is - 1. (When a term is written on it's own, it's coefficient is always 1, or if it has a negative/minus sign, - 1.)

Answer: The slope is - 1
