That's Intersecting Secants, and we get
EC × ED = EB × EA
(x+4)(x+4+1) = (x+1)(x+1+11)
(x+4)(x+5) = (x+1)(x+12)
x^2 + 9x + 20 = x^2 + 13x + 12
8 = 4 x
x = 2
Check: 3(14)=42 6(7)=42 good
Answer: 2
Answer: A
Explanation:
(Y-Y1)=m(X-X1) is the base formula for point slope. The points to plug in (X1, Y1) are in this case (2,1). Plugging in those points gives you the equation of Y+1=m(X-2). Then it asks for the slope. In this equation, m = the slope. So plug in (-5) for the slope and you get Y+1=-5(X-2).
Hope this helps!
