Using the below graph give the slopes of the straight lines tangent to the curve at points A, B, and C
Please provide the best answer for the statement.
The slope at point A is 5/5 = 1, at B it is zero, at C it is ?5/5 = ?1. To find these slopes divide the vertical distance of the tangent by the horizontal distance. At point C the line slopes down, so the vertical distance is negative when the horizontal direction is positive.
