Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
Complete the table for the equation y = 3x + 2 for x = 0, 1, 2, 3.
[2 marks]2.
Plot the graph of y = -2x + 4 using the grid. (Plot points for x = -2, 0, 2).
[3 marks]3.
Identify the slope (m) and y-intercept (c) of the equation y = -5x + 7.
[2 marks]4.
Calculate the value of y when x = 4 in y = 2x - 1.
[2 marks]5.
Construct a graph for y = 0.5x + 1 and find the value of y when x = 10.
[3 marks]6.
Plot the points for y = 4x - 3 for x = -1, 0, 1, and draw the line.
[3 marks]7.
If the graph of y = mx + c passes through (2, 5) and (4, 9), find the values of m and c.
[4 marks]8.
A line has equation y = -3x + c. When x = 2, y = 1. Find the value of c and draw the line on the grid.
[4 marks]9.
A car travels such that its distance y (km) from a starting point after x hours is given by y = 60x + 10. Plot this graph for x = 0 to 3.
[3 marks]10.
A line's equation is y = 0.75x - 2. Find y when x = 8 and draw the line.
[3 marks]11.
Identify the errors in the following statement: 'The line y = 2x + 5 passes through (1, 7).'
[2 marks]12.
A line has a slope of 3 and passes through (0, -4). Write its equation in y = mx + c form and plot it.
[4 marks]13.
Challenge: The line y = -1/2x + c passes through (4, 0). Find c and describe the line's steepness and intercepts.
