For this case we must find the slope of the following equation:
By definition, the point-slope equation of a line is given by:
Where:
: It is a point through which the line passes
m: It's the slope
So, the slope of the given equation is:
Answer:
Option D
Since 4x/5 is the reciprocal of 1/20, that means that 4x/5 = 20/1, or 20. Using this info, we can form the equation . From there we can solve for x.
Firstly, multiply both sides by 5:
Next, divide both sides by 4 and your answer will be
Answer:

Step-by-step explanation:
To factorise the quadratic consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x term.
product = 2 × - 6 = - 12 and sum = + 11
The factors are + 12 and - 1
Use these factors to split the middle term
2x² + 12x - x - 6 = 0 ( factor the first/second and third/fourth terms )
2x(x + 6) - 1(x + 6) = 0 (factor out (x + 6) )
(x + 6)(2x - 1) = 0
equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
2x - 1 = 0 ⇒ x =
