Answer:
x≤-2
Step-by-step explanation:
it would be that because if the graph is going to the left that means it is less than x and the opposite is for greater than. Now if there is a closed circle that means the sign is equal to hence the line under the sign. So therefore it's x≤-2
y=-1x+8
idk what to do here
Slope=change in y/change in x (y2-y1/x2-x1)
Slope=-2-(-5)/3-0=3/3=1
answer: slope=1
