$\bf (\stackrel{x_1}{-4}~,~\stackrel{y_1}{3})~\hspace{10em} slope = m\implies -4 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-3=-4[x-(-4)]\implies y-3=-4(x+4)$

$\bf y-3=-4x-16\implies y=-4x-13\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}$

Mathematics

360 Adults

Step-by-step explanation:

Let's represent the number of Adults with x.

Number of children = 2 * x = 2x.

The total amount collected for both children and adults = 1080.

Therefore, to know the number for adults we use the expression:

x + 2x = 1080

3x = 1080

Divide through by 3

x = 1080/ 3

x = 360.

Therefore, there are 360 adults.

Children would 2x

= 2*360

=720
