The given equation is:

y = -10x + 1
Slope of this equation = -10

New line will be perpendicular to this line, so slope of new line = 1/10

So, we are to find the equation of a line with slope 1/10 and passing through (5,7). Using the point slope form we can write

y - 7 = 1/10 ( x - 5)
y = x/10 -1/2 + 7
y = x/10 + 13/2
⇒
x/10 - y = -13/2

So option C gives the correct equation of the new line

Answer:

$\boxed{43.48 \, \%}$

Step-by-step explanation:

The formula for calculating percentage is

$\text{Percentage} = \dfrac{\text{Part }}{\text{Whole}} \times 100 \, \%$

The "part" is the number of single-shot espressos

The "whole" is the total number of espressos.

$\begin{array}{rcl}\text{Total espressos} & = & 46\\\text{-Single-shot espressos} & = & 26\\\text{Double-shot espressos} & = & 20\\\end{array}$

$\text{ \% Double-shot}=\dfrac{20}{46} \times 100 \, \% =\mathbf{43.48 \, \%}\\\\\boxed{\mathbf{43.48 \, \%}} \text{ of the espressos were double-shot}$
