Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
On the graph, a line passes through the points (2, 4) and (6, 10). Calculate the slope (m) of the line.
[3 marks]2.
Using the points (2, 4) and the slope you found, determine the y-intercept (c) of the line.
[3 marks]3.
Write the equation of the line in the form y=mx+c based on the previous questions.
[3 marks]4.
Plot the line y=2x+3 on the provided grid. Label the points (0, 3) and (2, 7).
[4 marks]5.
A recipe requires 3 cups of flour per batch, and the total flour used (y) depends on the number of batches (x). If the total flour used is 15 cups, how many batches are made? (Use the line y=3x)
[4 marks]6.
Identify the mistake in interpreting the line y=1.5x+1 if a student says it represents the total cost of ingredients, where x is the number of ingredients added.
[2 marks]7.
Construct a line graph from the points (1, 2), (4, 5), and (7, 8). What is the slope of the line?
[3 marks]8.
Given the line y=0.5x+2, what is the total flour used for 10 batches if each batch requires ingredients represented by the line?
[3 marks]9.
A cooking supplier charges $2 per ingredient plus a fixed fee. If the total cost for x ingredients is modeled by y=2x+5, how much would 8 ingredients cost?
[3 marks]10.
Challenge: If a line passes through (3, 5) and (7, 11), construct its equation. Then, determine how many ingredients (x) are needed if the total cost (y) is 17 in the context of the supplier problem.
