Which kind of function best models the data in the table? graph the data and write an equation to model the data.

linear; y = x – 1

linear; y = –x – 1

quadratic; y = x2 – 1

exponential; y = 3x – 1

Linear; y=-x - 1

The slope is negative since it’s decreasing. So it’s not the first equation. It’s not a quadratic equation because there is no forming U shape for this data. It’s not a exponential function because the slope is not 3 and a exponential function is in the form y=a(b)^x

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.
