What It Is: This is an exit ticket worksheet titled 'Oil Changes and Engine Repairs'. It presents a table of data showing the relationship between the number of oil changes per year (x-variable) and the cost of engine repairs (y-variable). The worksheet includes questions requiring students to plot the data, determine the correlation, draw a line of best fit, write the equation of the line, interpret the slope and y-intercept in context, and make predictions based on the data. Grade Level Suitability: This worksheet is suitable for high school, specifically Algebra 1 (as indicated by the code M-A1-6-3). It requires understanding of linear equations, graphing, data analysis, and interpreting slope and y-intercept, which are core concepts in Algebra 1. Why Use It: This worksheet helps students practice and apply their understanding of linear relationships and data analysis in a real-world context. It reinforces skills such as graphing, finding the equation of a line, interpreting slope and y-intercept, and making predictions based on a linear model. It encourages critical thinking about the relationship between variables. How to Use It: Students should first plot the data from the table on a separate sheet of graph paper. Then, they should answer the questions in order, drawing a line of best fit on their graph and using it to determine the equation of the line. They should then interpret the slope and y-intercept in the context of oil changes and repair costs. Finally, they should use their line of best fit or equation to estimate repair costs for a given number of oil changes and vice-versa. Target Users: This worksheet is designed for Algebra 1 students who are learning about linear relationships, graphing, data analysis, and interpreting slope and y-intercept. It is also suitable for teachers looking for an exit ticket or assessment to gauge student understanding of these concepts.

Algebra 1 worksheet: Explore correlation & line of best fit with oil change data. Interpret slope & predict repair costs. Great for high school!
