List two coordinates of two locations that, when connected, create a positive slope. Prove they are positive by putting them into the slope formula. List two coordinates that, when connected, create a negative slope. Put into slope formula. my positive points are (2,5) (12,19) my negative points are (12,19) (21,5) (Theyre the two sides of a triangle. Im a little confused on how to put them into slope form.

    okay so the slope is 7/5 and the y intercept is 11/5 and then the formula is y=mx+b so it would be y=(7/5)x+11/5?
