1. 12 mph, 24 miles
2. m=4, y=22
3.15/1, $1500
4. x=30 y=60, k cheaper, j cheaper
If a line is parallel to another line,Then the gradients are the same.So m=4 .Using general formula for str8 line, y=mx+c
![y = 4x + c](https://tex.z-dn.net/?f=y%20%3D%204x%20%2B%20c)
sub in coorfinates (1,13)
![13 = 4 + c](https://tex.z-dn.net/?f=13%20%20%3D%204%20%2B%20c)
So C=9.
The answer is 130.8 hope it helps
