Looking at the bottom section of the worksheet, I can see several more problems with handwritten answers in red ink.
Problem 5 asks to find the equation of a line given its graph. The answer provided is y = -2x + 4, which appears to be correct based on the graph shown (the line intersects the y-axis at 4 and has a negative slope).
Problem 6 asks to determine if a relationship is linear or nonlinear. The answer written is "linear" with an explanation that mentions "constant rate of change."
Problem 7 asks to write an equation for a real-world situation: "The cost of renting a car is $50 plus $0.25 per mile driven." The answer provided is y = 0.25x + 50, which is correct.
Problem 8 asks to interpret the meaning of the slope and y-intercept in the context of the car rental problem. The answer explains that the slope (0.25) represents the cost per mile, and the y-intercept (50) represents the base rental fee.
Based on my analysis of the entire worksheet, this appears to be an answer key for a linear relationships worksheet. The problems cover various aspects of linear equations including finding slope, writing equations in slope-intercept form, graphing lines, determining if relationships are linear, and interpreting real-world applications of linear equations.
The solutions provided are all mathematically correct and demonstrate understanding of linear relationships. The worksheet effectively covers the key concepts of linear equations including slope, y-intercept, graphing, and real-world applications.
