Answer:
the difference is the slope
Step-by-step explanation:
y = mx+b
m is the slope
b is the y-intercept
2x+4
3x+4
4x+4
the m constant changes meaning the slope is the difference
1 * 12 = -40
12 = -40
Since its not possible for twelve to equal negative-forty, than there is no answer for this equation.

:

Verify that the point of intersection occurs at 
Distance or meters and speed
It would be B, because BC does not necessarily have to be equal to CE, as they are not congruent
