Answer:
Height of each riser = 7.75 inches
Step-by-step explanation:
We are told that the distance between two floors is 9'-0 1/2”. This is 9ft 0.5inch
Let's convert to inches.
From conversion values, we know that 1ft = 12 inches
Thus, 9ft = 9 × 12 inches = 108 inches
Thus, total distance between two floors = 108 + 0.5 = 108.5 inches
Now,we are told there are 14 risers between this two floors distance.
Thus;
Height of each riser = 108.5/14
Height of each riser = 7.75 inches

Answer:
y=2x+1
Step-by-step explanation:
y=mx+b
-5=2(-3)+b
-5=-6+b
1=b
Plug it in to get y=2x+1
Answer:
Since the values vary from 0.5 to 4.5, let's take 5 intervals of width 1 unit each
