anonymous · Answer

use the formula for the slope 
$$\frac{125.651-118}{5.1-5}$$

anonymous · Answer

hmmm... is that " y = $$x ^{3} -7$$ " ?

anonymous · Answer

I didn't get that but I think I entered it incorrectly

anonymous · Answer

what did you get as a number?

anonymous · Answer

$125.651-118=7.651$ then divide by $.1$ same as multiply by 10 you get $76.51$

anonymous · Answer

I wasn't dividing by .1 I left it at 7.651

anonymous · Answer

ah that was the mistake

Thank you

hmmm... I didnt get the part where you wrote the equation "y = x3-7"... what was the point of that ?.. well, if you got it, thats fine then ^^
