The equation of the line passing through those two points is y=0x+1
First let's make both the miles and the hours ran improper fractions:

So, to find our miles per hour, we have to divide the miles by the hours to get: 
X= -2 y=3, long explanation but thats the answer i got.
The image that shows the reflection of DFEG over the x-axis is the FIRST option. The x-axis is the mirror line. The distance from the mirror line to the reflected shape equals to the distance from the original image to the mirror line.
