Answer:
D. 1 m
Step-by-step explanation:
100 cm = 1 m
This is a conversion factor
20% goes into 100% 5 times. So you do 480 times 5, which is 2400. So you answer is 2400.
Parallel lines have the same slope, in this case 3.
To find the y intercept we plug in the points (2,1) into y=mx+b, with 2 being x and 1 being y.
1=3(2) + b
Solve this and you get -5 as the y intercept.
The equation is y=3x-5
