Consider the graph and equation, y = 3x, that represent Alonso’s walking speed. What relationship is represented by this equation and graph? What would the points (3, 9) and (5, 15) represent? ;
x + y = 40 2 x + 4 y = 100 2 x + 2 y = 80 2 x + 4 y = 100 2 y = 20 y = 10 x = 30 You've got 30 2-point questions and 10 4-point questions.
The test contains 30 two-point questions and 10 four-point questions. This is determined by using a system of linear equations to represent the total number of questions and total points. Through solving these equations step-by-step, the counts of each question type were found.
