Answer:
20
Step-by-step explanation:
⇔ We can set up an equation using the information given to us
We can that 16 is equal or the same as, one and two tenths times a number which is 'x' added to negative 8
⇔ The minus cancels out the plus
⇔ Add 8 to both sides to isolate
⇔ Convert to improper fraction to make solving easier
⇔ Multiply both sides by 10 to isolate 12x
240 = 12x
⇔ Divide both sides by 12 to isolate x
20 = x
→ The 'number' is 20

Step-by-step explanation:
Option (1)
The slope of the graph is 60.
From the graph attached,
Slope =
=
= - 60
False.
Option (2)
y-intercept gives the initial distance, in miles from Exit 34.
True.
Option (3)
y-intercept of the graph is 3.5
Since, y-intercept of the graph is 210.
Therefore, Option (3) is False.
Option (4)
Slope gives the rate, in miles per hour, at which the distance to Exit 34 changes over time.
True.
