Answer:
25. No slope
Step-by-step explanation:
25. Y2 - Y1 / X2 - X1
= -8 - (-3) / 9 - 9
= -5 / 0
= no slope; straight line
Use this formula (Y2 - Y1 / X2 - X1) for each ques.
You answered would be n is greater or equal to 4 but u have to us that symbol
X^2-X-6=(X-3)(X+2)
(X+2)/(x+2)=1
Which just leaves (x-3)
X=3
