What does the slope of the curved line at point A shown in the above figure equal?
What will be an ideal response?
The slope of a curved line equals the slope of a straight line that touches the curved line at only that point. And, the slope of a straight line equals the change in variable on the y-axis divided by the change in the variable on the x-axis. Measure the slope of the straight line from point A to where the line crosses the x-axis, at 15. Thus the straight line has a slope of (30 – 0 )/(10 – 15 ) = -6. Therefore the curve line at point A also has a slope equal to -6.
