2 answers:
It's a pattern, you add three to every row. (1st row) 6+3=9, (second row) 9+3=12, (third row) 12+3=15, (fourth row) 15+3=18, (fifth row) 18+3=21, (sixth row) 21+3=24, (seventh row) 24+3=27 (eighth row) 27+3=30.

Answer:
-7, 1, 9, 17
Step-by-step explanation:
- F1=4*4+9=-16+9=-7
- F2=4*2+9=-8+9=1
- F3=4*0+9=0+9=9
- F4=4*2+9=8+9=17
7, if it was plus. but the question says suntraction.
The slope
m = (y2 - y1)/(x2 - x1)
m = ( 38 - -2)/ (-29 - -64)
m = 40/35
simplify
m = 8/7
