The x-intercept of -2 gives us an idea that point (-2,0) if found along the line. The y-intercept of -1, tells us that point (0,-1), this also tells us that b = -1.
Now that we have two points, we can solve for slope m

Now that we have both m and b. Substitute these values to the slope intercept form
Answer:
b
