Question

Find the rate of change /slope between its ordered pairs

(-5,13) and (1,1)
(-5,14)and (12,-21)
(1,1)and(12,-21)​

Answer 1

1.) -2

2.) -2

3.) -3

Explanation:

Since we can't make a graph, we can make a table

(-5,13) and (1,1)

x y

-5 13

1 1

From 13 to 1, you subtract 12 ( y-section)

From -5 to 1, you add 6 (x-section)

Now we can do y/x

y/x = 12/6 = -2

The slope for this first one is (-2).

(-5,14) and (12,-21)

x y

-5 14

12 -21

From 14 to -21, you subtract 34

From -5 to 12, you add 17

Now we can do y/x

y/x = -34/17 = -2

The slope for this second one is (-2)

(1,1 )and (12,-21)​

x y

1 12

12 -21

From 12 to 21, you subtract 33

From 1 to 12, you add 11

Now we can do y/x

y/x = -33/11 = -3

The slope for this third one is (-3)
