Attempts: 1.322Average: 1.8 / 27. Tangent lines and the slope along a curveUnderstanding SlopeThe blue curve on the following graph shows the height of an airplane over 10 minutes of flight. The two black lines are tangent to the curve at thepoints indicated by A and B.
SessionTimeout59:46
Points:1 / 1Close ExplanationThe slope of the blue curve measures the plane’srate of ascent . The unit of measurement for the slope of the curve isfeet per minute Explanation:The slope of a line measures how much the vertical coordinate of the line changes in relation to the horizontal coordinate. Therefore, since theblue line shows the relationship between altitude and time, the slope of the blue line measures how quickly altitude changes over time; in otherwords, it measures the rate at which the plane is ascendingIn this case, the rise, or vertical change, is measured in thousands of feet; and the run, or horizontal change, is measured in minutes.
