ANSWER and EXPLANATION
We have the four cordinate points:
(-6, 10), (-4, 7), (-2, 4), and (0, 1)
The first thing we can observe about these points is that there is a constant rate of change between the x cordinates and the y cordinates.
The x coordinates change by a value of 2 and the y coordinates change by a value of -3.
Also, we can try to plot these points on a graph:
It is interesting to see that all four points lie on the same straight line.
This agrees with the fact that the rate of change (slope) between the points is constant, since they lie on a straight line.
