Is y =3/4x +2 And -6x+8y=16 parallel or coincident

(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)

Plot the points (0,6), (3,15.8), and (9.5,0) using the graphing tool, and find the function
