Which one is the positive slope A.) (2,-3,) and (1,-2), B.) (0,0) and (3,-3), C.) (-1,-1) and (5,4) , D.) (-3,0), (9,0)

C is the positive slope! (5/6)

I hope this helps! Please mark brainliest :)

Step-by-step explanation:

Slope formula:

(y2-y1)/(x2-x1)=m

A. (2,-3,) and (1,-2)

(-2+3)/(1-2)=m

1/-1=m

-1=m

B. (0,0) and (3,-3)

(-3-0)/(3-0)=m

-3/3=m

-1=m

C. (-1,-1) and (5,4)

(4+1)/(5+1)=m

5/6=m

D. (-3,0), (9,0)

(0-0)/(9+3)=m

0/12=m

0=m

the discriminant is 64 + 4*1*12 = 112

this is prime.
