You can save a web page a couple of different ways. First you can simply highlight all the text and graphics on the page by pressing Ctrl-A on the keyboard or going to the Edit menu and choosing Select All. Then you can paste it into a program such as Word and save it to your disk. Keep in mind that the formatting most likely will not be exactly the same as it was on the web page.
Another way to save the page is to go to the File menu and choose Save As. Then you can pick Web Archive, single file to save the text and images to one file. Or you can choose Web Page, complete which will save the text as an htm document and the images in a separate folder. Keep in mind that you will need to keep the htm document and the image folder together to be able to have the images show on the page when you open the htm file.
