Answer:
PEMDAS
Step-by-step explanation:
Divide the speed value by 1.609,
1kilometer per hr=0.621mph
80kph=49.7097Mph
The y-intercept is changed from 2 to -4.
That means that the point that the graph crosses the y axis has been moved down by 6.
Since the slope of the line has not changed, this just means the graph of the line will be moved down by 6.
Hope this helps!
