<h2>Solution :- </h2>
Let the number be "x" , then according to the question :
• 2x - 12 = -8
Further solving
→ 2x = -8 + 12
→ 2x = 4 .
→ x = 2
Step-by-step explanation:

Answer:

Step-by-step explanation:
slope is the change in y over the change in x.
change in y is 14-18= -4
change in x is 30-(-20)= 50
so the answer is -4/50
we can factor out 2 from both equations to simplify the fraction. this gives us -2/25
