If f(x)=x2−1; x0=−1 (a) Find a formula for the slope of the tangent line to the graph of function at a general point x=x0
(b) Use the formula obtained in part (a) to find the slope of the tangent line for the given value of x0.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

i think the answer is c sorry if it's wrong

160 cm

step-by-step explanation:

you have to add all the sides together
