Answer:
The slope is dy/dx= -1/2
Step-by-step explanation:
Y-3= -1/2(X -2)
Y= -1/2x +2/2 +3
Y= -1/2x +1+3
Y= - 1/2x +4
The slope dy/dx= -1/2

45-49 - - - 47 - - - 13 - - - 611
50-54 - - - 52 - - - 3 - - - 156
55-59 - - - 57 - - - 1 - - - 57
Mean of grouped data:
Sum of (F × X) / sum of F
1540 / 35 = 44
