The equation would be L = 1d + 45
After 21 days it would be
L = 1(21) +45
L = 21 + 45
L = 66 miles after 21 days

Notice that 2y and 3x are vertical angles, which means they are equal.
2y=3x

the four angles below the line AB make a sum of 180
 3x+x+2x+x=180
7x=180
x=180/7

2y=3x=3*180/7=540/7
y=270/7≈38.6
d is the answer.

The line extends to the right, so the answer must be C or D. The dot is not filled in, which means -2 is not included in the solution. Therefore the correct answer is C: x is greater than -2.

Hope this helps.
