PROGRAM:SLOPE
:Input "Y2=",Y2
:Input "Y1=",Y1
:Input "X2=",X2
:Input "X1=",X1
:(Y2-Y1)/(X2-X1)>A
: Disp A>Frac
it should work |

Oh, and a word of advice: I strongly suggest you don't submit it to a site because there are a bazillion others out there (in case you were thinking about it). |

Why does anyone need a program to plug-and-chug the slope formula anyway... |

Total Posts: 310 | Precious seconds? By having an 89 instead of using the 8x's >Frac command? Please. If that little time makes that much of a difference, you deserve a bad grade anyway.
Ah screw it. After all, we live in the age where students can't be bothered to memorize things like the BLOODY SIMPLE slope formula. |
