Could someone please give me the answer to this?

Asystem of equations has 1 solution.if 4x-y=5 is one of the equations , which could be the other equation ?

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
