Answer:
-3
Step-by-step explanation:
To find slope you first need to pick to points where the line crosses a corner.
Slope=
I'm using the points (0,-2) and (-1,1). You can either count up and over for the slope or use the slope equation
y2=second y point
y1=first y point
x2=second x point
x1=first x point
Now you just solve
or -3
When we say "closed under addition" in the context of rational numbers, we mean to say that when we add up rational numbers then, the sum is also a rational number.
From the given choices above, the one that should the characteristic of being "closed under addition" is only fourth equation. Both 1/2 and 0.5 are rational numbers. On the other hand, 1 is also a rational number.
