Question 1: Write the Y-intercept of the equation y = 3x + 5.

Answer: 5

Question 2: Identify the Y-intercept from the equation y = -2x + 7.

Answer: 7

Question 3: Given the equation y = 4x - 2, what is the Y-intercept?

Answer: -2

Question 4: Plot the graph of y = 2x + 3. What is the Y-intercept?

Answer: 3

Question 5: Construct a line on the grid with a Y-intercept at -4 and passing through (2, y). Plot the line and find the Y-intercept.

Answer: -4

Question 6: What is the Y-intercept of the equation y = -0.5x + 6?

Answer: 6

Question 7: The equation of a line is y = 5x + b. If the Y-intercept is at (0, -3), what is the value of b?

Answer: -3

Question 8: Find the Y-intercept of the equation y = 7x - 9.

Answer: -9

Question 9: Given the equation y = 1.5x + 4, explain how you identify the Y-intercept.

Answer: The Y-intercept is the constant term in the equation, which is 4, indicating the point (0, 4) where the line crosses the Y-axis.

Question 10: A line passes through (0, 2) and (3, y). Write the equation of the line and identify its Y-intercept.

Answer: y = (2/3)x + 2

Question 11: If a line has a Y-intercept at (0, 10) and a slope of -2, write its equation and describe the intercept.

Answer: The equation is y = -2x + 10, and the Y-intercept is at point (0, 10).

Question 12: Identify the mistake in the following statement: 'The Y-intercept of y = 3x + 4 is at (4, 0).'

Answer: The mistake is that the Y-intercept occurs at the point (0, 4), not (4, 0).
