.15 × 60 = 9
Answer:
The y-intercept in this case is 4800
Step-by-step explanation:
The equation of a line graph is ;
y = mx + c
with respect to the given equation in the question, the y-intercept in this case is 4,800
In this case the y-intercept represent the height from which the plane starts to descend
420÷8=52.5
the answer is 52.5 words per minute
⇒ Choose three values for 
and substitute in to find the corresponding 
values.
