Answer:
C
Step-by-step explanation:
the answer is c because if input the numbers into the slope formula y2 - y1 over x2 - x1 it equals 3 - 0 over 2 - (-1) and 3 - 0 would be 3 and 2 - (-1) would also be 3 because the two subtraction signs cancel out and turn into an addition sign so it would be 3 over 3 or 1 in simplified form
