Hello, Im trying to insert a trend line and a slope for my chart. I click on the point and nothing shows. I click on the chart itself and nothing shows. I've already tried this on a different browser and no result. I'm using a MacBook Air if it helps. I need this to work for assignment. I linked an image of what it looks like and again there is no side window that can have me insert the trend line and the slope. Please help!
