Graph the circle: (x+8)^2 + (y+5)^2= 121

When only separate discreet points are graphed it is called?

X+ y = 5 ; x - y =3 solve using linear combination

If you have a set of parallel lines a and b cut by transversal x, if angle 1 = 167 degrees, what is angle 4 and why. also what is the measure of angle 5 and why? you need to use the names of the angle relationship and explain.
