Determine any data values that are missing from the table, assuming that the data represent a linear function.

x y

-12 17

-10 19

-8?

? 23

a. Missing x:-6

Missing y:22 c. Missing x:-7

Missing y:20 b. Missing x:-7

Missing y:22 d. Missing x:-6

Missing y:21

(-12,17), (-10,19)

slope = (19 - 17) / (-10 - (-12) = 2 / (-10 + 12) = 2 / 2 = 1

y = mx + b

slope (m) = 1

(-12,17) ... x = - 12 and y = 17

sub and find b, the y int

17 = 1 (-12) + b

17 = - 12 + b

17 + 12 = b

29 = b

so ur equation is : y = x + 29

so when x is - 8

y = - 8 + 29

y = 21 <===

and when y = 23

23 = x + 29

23 - 29 = x

- 6 = x <===

missing : y = 21 and x = - 6
