45 points If you help me with these please ?ASAP

Step-by-step explanation:

the first graph has points (-1, -1) and (2, -2)

slope m = (y2-y1) / (x2-x1) = (-1+2)/ (-1-2) = 1/-3 = -1/3

the second graph has points (0, -3) and (2, 0)

slope m = (y2-y1) / (x2-x1) = (-3-0)/ (0-2) = -3/-2 = 3/2

for the table

x.         y

-3.        4

0.        1

slope m = dierence in y /diference in x = 4-1 / -3-0 = 3/-3= -1

cosine
