Thank you for your time! My excel isn't working, please help me with a graph from the table below. All references are also below. Thank you for your time!

The magnification, M, is the ratio of image size to object size. If the image is larger than the object, M is greater than 1, and if it is smaller, M is smaller than 1. The convention in geometric optics is that if the image is inverted, M is negative and M is positive if the image is not inverted relative to the object. In this lab, you will use the Thin Lens Equation to make a careful measurement of the focal length of a lens and make qualitative observations about image magnifications.Use the graph provided or spreadsheet software, such as Excel or Google Sheets, to plot the reciprocal of the object distance (1/d ) over the reciprocal of the image distance (1/d ) for each trial in Data Table 1. Find and include the best fit line for the graph. Record the slope and y-intercept of the line
