What is the point-slope form of a line with slope 2 that contains the point (1, 3)?

$\bf \begin{array}{lllll}
&x_1&y_1\\
% (a,b)
&({{ 1}}\quad ,&{{ 3}})\quad

\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 2
\\\\\\
% point-slope intercept
y-{{ y_1}}={{ m}}(x-{{ x_1}})\implies y-3=2(x-1)\\

At a certain hospital 39080 patients had their falls reported in the winter of 2004, thisrose to 42045 patients in the winter of

Natali [406]

Answer:

Percentage rise in patients from 2004 to 2014 = 7.59%

Explanation:

The number of patients in 2004 = 39080

The number of patients in 2014 = 42045

Increase in the number of patients = (The number of patients in 2014) - (The number of patients in 2004)

Rise in the number of patients = 42045 - 39080

Rise in the number of patients = 2965

$\begin{gathered} \text{Percentage rise in patients = }\frac{\text{Rise in the number of patients}}{\text{Number of patients in 2004}}\times100 \\ Percentage\text{ rise in patients = }\frac{2965}{39080}\times100 \\ \text{Percentage rise in patients = }7.59\text{ \%} \end{gathered}$

Percentage rise in patients from 2004 to 2014 = 7.59%
