    In the trend line equation y = mx + b, what does the slope (m) represent?

  2. MultiChoice

    In line y = 5x + 60 relating study hours (x) to score (y), slope = 5 means:

  3. MultiChoice

    In equation y = 1.5x + 4 for plant height (y) in cm after x days, slope = 1.5 means:

  4. MultiChoice

    Equation y = -1200x + 25000 gives car value (y) after x years. Slope = -1200 means:
