ANSWER

The required equation is

y = 5x + 1



EXPLANATION

The given line passes through the point

(5,0) \: and \: (0,1)


The slope of this line is given by the formula,

m=\frac{y_2-y_1}{x_2-x_1}


This implies that,

m =  \frac{1 - 0}{0 - 5}

m =  -  \frac{1}{5}


The product of the slope of the two perpendicular lines should be negative one.

Thus,

m_1\times m_2=-1
This implies that,


-  \frac{1}{5} \times m_2=-1


We multiply through by
- 5
to obtain,


m_2=-1 \times  - 5

m_2=5
Therefore the slope of the line perpendicular to the given line is
5.


We use the slope intercept formula
y =m x + b

where
b = 1
is the y-value of the y-intercept.



We therefore have,


y = 5x + 1

as the required equation.


The correct answer is C.

Answer:

x = -14

Step-by-step explanation:

\frac{x}{2} = -7

multiply 2 on both sides

the 2's cancel out on the fraction side, leaving x = -7(2)

multiply -7 and 2 to get -14

x = -14
