Question 1: Identify the slope (m) and y-intercept (c) of the line shown on the graph.

Answer: m=3, c=1

Question 2: Write the equation of the line that passes through the points (1, 2) and (4, 5). Show your working.

Answer: y=1x+1

Question 3: Given the line y=2x+4, plot this graph on the grid provided.

Answer: Student plots the line correctly on the grid.

Question 4: A line passes through (0, 5) and has a slope of -2. Write the equation of this line.

Answer: y=-2x+5

Question 5: Construct a line on the grid with a slope of 1/2 and y-intercept of -3. Show the line on the graph.

Answer: Student draws the line y=0.5x-3 accurately.

Question 6: The line y= -4x + 2 crosses the y-axis at what point? Explain how you know.

Answer: At (0, 2), because the y-intercept is 2.

Question 7: Find the slope of the line passing through (2, 3) and (5, 9).

Answer: m=2

Question 8: Plot the line y=-x+4 on the grid. What is the y-value when x=3?

Answer: y=1

Question 9: Determine the equation of the line that passes through the points (0, -2) and (2, 2).

Answer: y=x-2

Question 10: A graph shows a line with a slope of 0.75 and y-intercept at -1. Plot this line and write its equation.

Answer: y=0.75x-1

Question 11: Identify and correct the mistake in the following line equation derived from a graph: y= -2x + 4, when the line actually has a slope of 2 and crosses y at 4.

Answer: Incorrect; the slope should be 2, so the equation is y=2x+4.
