slope=y2-y1/x2-x1
slope=2-(-1)/1-2
slope=3/-1
slope= -3
Answer:
Step-by-step explanation:
7) 2ab + 4ac = 2*a*b + 2 *2 *a*c
= 2a(b + 2c)

8) ac - a²c² = c( a - a²c)
bc - abc = c(b - ab)


9) b²+ 4b - 5 = b² + 5b - 1b - 5
= b(b + 5) - 1(b + 5)
= (b +5)(b - 1)
b² + 8b + 15 = b² + 5b + 3b + 15
= b(b + 5) + 3(b + 5)
= (b + 5 )(b + 3)
