Hot air is less dense than cool air, so hot air will rise above cool air. Increasing the air temperature inside a hot air balloo

n makes it lighter than the surrounding air, so the balloon can lift up. The density of hot air is about 0.25kg/m^3 less than that of cool air, which means a cubic meter of hot air can lift about 0.25kg.
What is the minimum volume of hot air needed to lift a hot air balloon carrying

First, find the slope of the line. Use the two points given, (-4,0) and (4,2), in the slope formula rise over run. The change in rise is 2 and the change in run is 8, meaning that the slope is 2/8, simplified to 1/4. The y-intercept is 1, shown by the graph and the dashed line and shaded area means that the inequality symbol must be <. Slope-intercept form is shown as y = mx + b, so after putting our information in to the equation the answer is y < 1/4x + 1. Hope this helps!
