Answer :
Answer:
-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.)
