Iwill mark the best brainiest

Inputs are the x-values and outputs are the y-values.

a) I chose the (x, y) coordinates of: (-4, -3) and (-5, -11)

Difference in inputs (x): -4 - (-5) = -4 + 5 = 1

Difference in outputs (y): -3 - (-11) = -3 + 11 = 8

8

b) I chose the (x, y) coordinates of: (-3, 5) and (-5, -11)

Difference in inputs (x): -3 - (-5) = -3 + 5 = 2

Difference in outputs (y): 5 - (-11) = 5 + 11 = 16

16

c) I chose the (x, y) coordinates of: (-2, 13) and (-5, -11)

Difference in inputs (x): -2 - (-5) = -2 + 5 = 3

Difference in outputs (y): 13 - (-11) = 13 + 11

24

d) ratio of output to input =

a. = = 8

b. = = 8

c. = = 8

The ratios are the same.

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
