Answer:
Linear
Step-by-step explanation:
You can either graph the points or calculate the slope between them. The slope will be Rise/Run:
(-7,10) to (-1,2.5):
Rise = (2.5 - 10) = -7.5
Run = (-1 - (-7)) = 6
Slope (Rise/Run) = -7.5/6 = -1.25
(-1,2.5) to (9,-10):
Rise = (-10 - 2.5) = -12.5
Run = (9 - (-1)) = 10
Slope = (-12.5/10) = -1.25
The slopes are the same, so it is a straight line.
