Digital Cameras and Linear Equations (Blog Post 7)

Eighth grade math students will take a picture using a digital camera, open it in Photoshop to crop and focus on a section of the photo. They will print it and then create a coordinate grid on the picture. They will record the order pairs, calculate the slopes, and write equations of lines connecting the two points. They will use a graphing calculator to check their work. They will then upload the pictures in PowerPoint and list their equations. Students will wrap it up writing a reflection of the activity.
