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

I know the answers, I just don't know how to get to the answers

5. 2

7. 1/4

9. 0

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

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
