(–12, –6)

(–5, 4)

(18, 19)     and     (14, 12)  

Step-by-step explanation:

use this cite:https://www.calculator.net/slope-calculator.html    

step 1.   choose 2 points are know

step 2.   write the slope(0,4)

step 3.    type in one ordered pair

and if it matches its the correct answer.

1/800 is the right answer

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
