Answer: 
Step-by-step explanation:
Equation of the line given ;

To find the slope of the line we will make y the subject of formula , that is


Therefore ; the slope = 
Two lines are said to be parallel if they have the same slope
This means that the slope of the second line = 
Using the formula
to find the equation of the line , we have





Answer:
18 7/8 or 18 21/24
Step-by-step explanation:
If two secants are drawn from a point lying outside a circle, then the product of one secant on its outer part is equal to the product of the other secant on its outer part.
DE*CE = AE*BE
DE = CD + CE = 1 + x + 4 = x + 5
AE = AB + BE = 11 + x + 1 = x + 12
(x+5)(x+4)=(x+12)(x+1)
x² + 4x + 5x + 20 = x² + x + 12x + 12
9x + 20 = 13x + 12
20 - 12 = 13x - 9x
8 = 4x
x = 8/4
x = 2
The correct answer is A.18
