Here I solved it for you on paper
Well im not good at this ,butt I'll tell you something. An open dot means that point is not included , soo something like y<208 would mean 208 is not included and have an open dot, butt a closed dot means the point is included, such as <_ 450. ( The line is supposed to be under < butt i don't know how to do that.) Hope this helps

x=8.975
