Answer:
0
Explanation:
You should prolly turn the line into slope intercept form, y = mx + b
m being the slope
b being the y intercept
The line intercepts the y-axis at -1 so b = -1
From the point of (0,-1) you go up one and left two, that means the slope is -1/2

y = 1 - 1
y = 0
When x = -2, y = 0
