Which kind of function best models the set of data points (–1, 22), (0, 6), (1, –10), (2, –26), and (3, –42)?

LINEAR. I arrived at that conclusion after solving for the slope.

m = y1 - y2 / x1 - x2 
m = 22 - 6 / -1 - 0 = 16/-1 = -16
m = 6 - (-10) / 0 - 1 = 16/-1 = -16
m = -10 - (-26) / 1 -2  = 16/-1 = -16

Which kind of function best models the set of data points (–3, 18), (–2, 6), (–1, 2), (0, 11), and (1, 27)? NONE OF THE ABOVE

3. What function can be used to model data pairs that have a common ratio? EXPONENTIAL

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
