Answer 4

jesus loves u

Answer 5

ok. that's good.
thank you

Answer 6

@jim_thompson5910 can you explain how da-jesus-train got this answer because I don't understand

Answer 7

which line? it doesn't say like it did last time

Answer 8

oh! oops one second

Find the slope of the line between 1990 and 1992

Answer 9

ok what are the coordinates here?

Answer 10

you only need to focus on the years 1990 and 1992

Answer 11

(1990,12) (1992,23)

Answer 12

use the slope formula from here

subtract the y coordinates and you get what?

Answer 13

1978 and 1969

Answer 14

focus on just the y coordinates, which are 12 and 23

subtract them to get what?

Answer 15

11

Answer 16

yep, now do the x coordinates

from 1990 to 1992 is a difference of how many years?

Answer 17

2

Answer 18

so the magnitude changes by 11 at the same time the number of years changes by 2

slope = rise/run = 11/2

Answer 19

put another way

slope = (change in y)/(change in x) = 11/2

Answer 20

thank you

Answer 21

no problem
