Two lines, a and b, are represented by the equations given below:

line a: 2x + 2y = 8
line b: x + y = 4

which statement is true about the solution to the set of equations?

Pranza plotted point a in the coordinate plane below.

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

Measure a and b and find their sum. how are the angles related?
