Coordinate Planes - Class 3

3.1 Coordinate Planes

• Plot points on a coordinate plane (e.g., C(3, 2) and D(-2, 4))
• Draw a square ABCD, positioning A and B below the x-axis
• Find coordinates of A and B
• Identify the quadrant where the intersection of diagonals AC and BD (point S) lies
• Shade points with an x-coordinate of 2 and a y-coordinate between 3 and 4

3.2 Patterns in Coordinate Planes

• Identify patterns in a sequence of triangles
• Determine coordinates of left vertex of a triangle (e.g., triangle 8)
• Given the left vertex of a triangle (e.g., (-50, 10)), find the left vertex of the triangle two places further to the left
• Understand the relationship between the triangle's position and their coordinates

3.3 Graphs in Coordinate Planes

• Analyze graphs showing distance to a destination (e.g., Assen) for Josh and Ruben
• Calculate the distance between Josh and Ruben at a specific time (e.g., 9:30 a.m.)
• Determine the duration Josh stays in Assen
• Identify the time when Josh and Ruben meet on the way back
• Break down Ruben's graph into four parts and calculate the speed (km/hr) for each part

3.3 Graphs in Coordinate Planes (Continued)

• Sketch graphs for various situations (e.g., Ryan cycling, Jasmin cycling with a break)
• Create corresponding distance graphs for these situations

3.4 Word Formulas

• Calculate annual cost of renting a dock, considering area (e.g., 50 + 10 * area)
• Determine difference in dock rental costs for different boat sizes (e.g., Mrs. Block's and Mr. Mast's)
• Calculate the area of a boat given the yearly dock rental cost(e.g. €470)
• Understand a scenario with a fixed fee and per-m² charge related to yearly dock rental, including a formula

3.5 Formulas with Letters

• Perform calculations with formulas involving variables (e.g., calculate 5a - 8 for a = 4; calculate 3 - 5b for b = 6; calculate 18 + c for c = 3)

3.5 Formulas with Letters (Continued)

• Evaluate expressions with variables and substitution (e.g., calculate 2 - 8(5 - d) for d = 7; calculate -2(3e) - 8 for e = 5; calculate 2f - 2(5g) for f = 5 and g = 10)

3.6 Graphs and Formulas

• Create a graph for taxi cost depending on distance (e.g., 5 + 2k, where k is distance in kilometers)
• Calculate a taxi fare based on given distance and company formula
• Calculate taxi fare using a different formula (e.g., Blue taxi formula: c = 5p + 1.5k)
• Create a graph for taxi cost depending on number of passengers and distance using the given formula
