Answer:
1) c (a,b)
2)The length of DB (I can't put the line on top)
3) AC
Slope =change of y over change of x
(2, −5) and (4, 1)
M= 1-(-5)/4-2
M=6/2
M=3
So the slope is 3.
If you need the equation
Y=mx+b
(4, 1)
1= 3(4)+b
1=12+b
1-12=b
-11=b
So equation
Y=3x-11
The answer to your question is c :)
Answer:
secθ = - 2
Step-by-step explanation:
Using the identity
sec²θ = 1 + tan²θ
= 1 + (
)² = 1 + 3 = 4 ( take the square root of both sides )
secθ = ±
= ± 2
Since secθ < 0 in the third quadrant , then
secθ = - 2
