Practice Questions

Answer all questions. Show your working in the grid spaces provided.
1.
Look at the graph below. What is the Y-intercept of the line? Write the coordinate.
[2 marks]
2.
Calculate the Y-intercept for the line passing through points (2, 1) and (4, 3). Show your work.
[3 marks]
3.
A graph line appears to cross the Y-axis at (0, -2). Which of the following might be a common mistake students make when reading this point? A) Confusing X and Y values B) Reading the wrong point on the axis C) Not noticing the line actually crosses the Y-axis
[1 mark]
4.
Construct a graph line that intersects the Y-axis at (0, 5) and passes through (3, 8). Plot these points on the grid.
[3 marks]
5.
A student claims that the Y-intercept is always the point where the line crosses the Y-axis. Is this correct? Explain your answer.
[3 marks]
6.
Read the graph below. The line crosses the Y-axis at (0, -4). The line also passes through (2, 0). Find the equation of the line.
[4 marks]
7.
In a real-world context, a car's speed over time is graphed. The Y-intercept occurs at time 0, at a speed of 60 km/h. What does this Y-intercept tell us?
[3 marks]
8.
A line crosses the Y-axis at (0, 7). If the line continues upward, what is the Y-intercept? Is this a mistake? Explain.
[3 marks]
9.
Identify the common mistake in reading the Y-intercept from a graph where the line appears to cross just below the Y-axis at (0, -0.5).
[2 marks]
10.
Given the graph where the line crosses the Y-axis at (0, 2), but the student marked (0, 3), what error did the student make? How can they correct it?
[3 marks]
