If I’m correct the right answer should be A. 1,680) If I’m wrong plz let me know
Step-by-step explanation:

Replace each of the x values given to see if they give 0.
0=(2/3)³+(2/3)²-1
0=(8/27)+(4/9)-1
0≠-0.259
0=(1)³+(1)²-1
0≠1
Therefore, you can see that the solution would have to be between 2/3 and 1.
Hope I helped :)

AVeraging is adding all of the numbers together with the dividing by a number of numbers you have.
M= y2-y1?x2-x1
m=4-(-1)/(-7)-8
m=5/-15
m=-3
The slope is -3
