This riddle activity has students writing linear equations in slope-intercept form, both from a graph and converting from standard form. There are 6 questions where students need to find the slope and y-intercept from a graph and 6 questions where students are converting from standard form. The last question requires students to match a graph to the equation in standard form, requiring them to do both converting and writing from a graph. After writing/converting the equation, students will find their answer in the chart on the back to find a letter to place in the corresponding number box. This will lead them to answering the cheesy riddle at the top of the page. The activity is self-checking, as students will immediately know if they got the answer right or wrong when they check the box for their answer on the back. Check out the preview to see every question to make sure this activity is the appropriate level for your students!
