Understanding Graphical Interpretations

This video tutorial explains how to interpret graphs by analyzing ordered pairs, vertical intercepts, and horizontal intercepts. It uses a graph where the input is the number of candles sold and the output is the profit in dollars. The tutorial demonstrates how to locate and interpret the ordered pair (120, 150), which indicates a profit of $150 when 120 candles are sold. It also explains the vertical intercept, showing a loss of $50 when no candles are sold, and the horizontal intercept, which is the break-even point where 30 candles are sold for zero profit.

What does the first value in an ordered pair represent in a graph?

• The horizontal intercept

• The input value

• The vertical intercept

• The output value

In the context of the video, what does the ordered pair (120, 150) signify?

• A loss of $150 when 120 candles are sold

• A break-even point at 120 candles

• 150 candles sold with a profit of $120

• 120 candles sold with a profit of $150

What is the vertical intercept in a graph?

• The point where the output is maximum

• The point where the input is maximum

If 30 candles are sold, what is the profit according to the horizontal intercept?

• $50 gain

• $30 loss

• $0 profit

• $30 profit

What is another term for the horizontal intercept when there is no profit or loss?

• Break-even point

• Surplus point

• Loss point

• Profit point

What is the significance of the break-even point?

• It indicates maximum profit

• It indicates a loss

• It indicates a profit

• It indicates no profit and no loss
