Find the slope between (-9, 7) and (-11, 6)
A. -2
B. 2
C. 1/2
D. -1/2
Explain why the answe4 is correct and why the answer is not corr4ct?
To find the slope between two points, we can use the formula:
slope = (change in y) / (change in x)
First, let's find the change in y:
change in y = 6 - 7 = -1
Next, let's find the change in x:
change in x = -11 - (-9) = -11 + 9 = -2
Now, we can calculate the slope:
slope = -1 / -2 = 1/2
Therefore, the correct answer is C. 1/2.
The answer is not correct because D. -1/2 is the negative of the correct slope, and the other options A. -2 and B. 2 are not the correct slope.
