Answer:
Step-by-step explanation:
First of all notice that slope has a negative value
Also notice that line cuts the y axis in -1
because of the symetry of the line you can deduce that the slope is -1, also you can calculate it using the fact that the points (-1, 0) and (0, -1) belongs to the line, the slope would be:
m=(0-(-1))/(-1-0)=-1
finally the equation is
y=-x-1
