linear functions unit test// unit 6 lesson 10

9. what is the slope of the line that passes through the pair of points (3/2, -2) and (-3, 7/3)?

a. -27/26
b. -26/27
c. 26/27
d. 27/26

Step-by-step explanation:

slope = (y2 - y1) / (x2 - x1)

(3/2,-2)x1 = 3/2 and y1 = -2

(-3,7/3)x2 = -3 and y2 = 7/3

now we sub

slope = (7/3 - (-2) / (-3 - 3/2) = (7/3 + 2) / (-3 - 3/2) =

             (7/3 + 6/3) / (-6/2 - 3/2) = (13/3) / (- 9/2) =

             13/3 * -2/9 = - 26/27 <

add an image !

step-by-step explanation:

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
