I am not sure but this is what I got-
217.39-14.95 to find the cost before the base fee. which is 202.44
then i did this= 202.44 / .84= 241
so the answer is 241 miles
7y = 8x - 14
7y= 7(6) Reason : Given
7y = 42
8x -14 = 42 Reason: Because 8x - 14 equals to 7y
8x = 42 + 14 Reason : Because we flip 14 on to the other side of the equation thus it becomes opposute of what it was.
8x = 56
× = 7

Slope intercept form is y = mx + b, where m is the slope. 5 is greater than 2 so that’s why y = 5x + 1 has a greater slope than y = /x + 5
