Full solution

Q. Find the yy-intercept of the line y=−3x−9y = -3x - 9. Write your answer as an integer or as a simplified proper or improper fraction, not as an ordered pair.
  1. Understand the equation: Understand the equation of the line.\newlineThe equation of the line is given in slope-intercept form, which is y=mx+by = mx + b, where mm is the slope and bb is the yy-intercept.
  2. Identify the y-intercept: Identify the y-intercept from the equation.\newlineIn the given equation y=−3x−9y = -3x - 9, the y-intercept is the constant term, which is −9-9.
  3. Write as integer: Write the yy-intercept as an integer. The yy-intercept is already given as an integer, so no further simplification is needed.
