Answer:
so looks like they want you to solve each of them first, then plot them on the number lines.
1) x+8 >= 18
subtract 8 from each side
x >= 10
so for this one you would plot the point (a closed circle, since it's greater than or equal to) on the ten, and draw an arrow pointing to the right
2) x-1 > 6
add 1 to each side
x > 7
for this one you would plot an open circle on the 7 and draw an arrow to the right
3) -7+x >= -8
add 7 to each side
x >= -1
for this one you would plot a closed circle on the -1 and draw an arrow to the right
4) x-1 <= 3
add 1 to each side
x <= 4
for this one you would plot a closed circle on the 4 and draw an arrow to the left
