Ade and abc are similar. which best explains why the slope of the line between points a and d is the same as the slope between points a and b?

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y

Suppose that g(x)=f(x+9) which statement best compares the graph of g(x) with the graph of f(x)
