How do you do question 3?

(08.01)consider the following pair of equations: x + y = −2 y = 2x + 10 if the two equations are graphed, at what point do the lines representing the two equations intersect? (−4, 2) (4, 2) (−2, 4) (2, 4)

Sam claims that cos x =sin y if x and y are congruent angels. is sam correct ?

Someone me! if you’re smart you can solve this!
