4x+y=7 i’m having trouble with this equation, it’s kind of complicated.

Which best describes the transformation that occurs in the graph? a) dilation b) reflection c) rotation d) translation

Which pair of lines is parallel? a. y=4x+1 and y+4=5 b. y=-2+x and 2y-2x=-2 c. y=1/4x + 2 and y-2=1/2x d. y=1/5x+1 and 5y+x= 10

Factor the polynomial, if possible. if the polynomial cannot be factored, write prime. 9n^3 + 27n^2 – 25n – 75
