Using substitution for systems of equations, solve, show work. y= -2x+16 -3x+5y= -11

The graph of g(x) is a translation of y = which equation represents g(x)?

The graph below shows the height of a projectile t seconds after it is launched. if acceleration due to gravity is -16 ft/s2, which equation models the height of the projectile correctly?

Can some one explain this i got sent this. is this a threat i’m scared
