    Question

    The y-intercept of the line y = –4x – 7 is

     

    1. -7
    2. -4
    3. 4
    4. 7

    hintHint:

    Y-intercept of a given line is the value of y-coordinate where x = 0

    The correct answer is: -7

      GIVEN-
      Equation of the given line- y = -4x - 7
      TO FIND-
      Y-intercept
      SOLUTION-
      We know that equation of a line in slope intercept form can be written as y = mx + c, where m = slope and c = y-intercept.
      Comparing the given equation i.e. y = -4x - 7 with y = mx + c, we get-
      y-intercept = c = -7
      FINAL ANSWER-
      Option 'a' i.e. '-7' is the correct answer to the given question.
