It should be "A"
On the number line, it shows that -4.5 is further and to the right of -2.3.
Hope that helps!
The slope for the first one would be:
y2-y1/x2-x1, so replace those with the coordinates and you'll get:
-3-1/-7-(-7) => -4/0 so I guess the slope is zero
the slope for the second one would be:
-3-(-3)/5-(-4)=> 0/9 I think this one would be undefined.
Check to make sure, though!
It will take 6.875h for the second car to overtake the first...
