Answer:
B
Step-by-step explanation:
The formula to determine slope is [tex]\frac{y-y}{x-x}[/tex].
Knowing this you can fill in the formula with the numbers: [tex]\frac{2-4}{-8+9}[/tex]
2 - 4 is -2, so the numerator is -2.
-8 + 9 = 1, so your denominator is 1.
Therefore, your fraction is [tex]-\frac{2}{1}[/tex], or simply -2.
