4 Which is the equation of a line parallel to a line with slope -3 and also
passes through (-6, 7).*
O y-7 = 1/3(x + 6)
Oy -7 = -3(x+6)
O y+7= 1/3(x-6)
Oy+7=-3(x - 6)

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
