Answer:
-3
Explanation:
To find slope you first need to pick to points where the line crosses a corner.
Slope=
![(Rise)/(Run)](https://img.qammunity.org/2021/formulas/mathematics/high-school/tmnlmtormy0aonmdl40wlugs9i6fxeyz2t.png)
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-y1)/(x2-x1)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/flm5n96lsu1pl0daqmknr0jcmu4wjdbkcc.png)
y2=second y point
y1=first y point
x2=second x point
x1=first x point
Now you just solve
or -3
