Question

Estimate the slope of the tangent line to each curve at the point (x,y).

Answer 1

7. On the x axis, from -2 to 2 is 4 units

On the y axis at -2 the tangent is at y 2, at x = 2 the line is at about y=3

The slope would be (3-2) / (2 - -2)

Slope = 1/4

9. The line is a straight line so there is no slope. Slope = 0
