Write an equation of the line that passes through the points (-2,-2) and (0,5)

marshall27 [118]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
&&(~ -2 &,& -2~) 
&&(~ 0 &,& 5~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{5-(-2)}{0-(-2)}\implies \cfrac{5+2}{0+2}\implies \cfrac{7}{2}
\\\\\\
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-2)=\cfrac{7}{2}[x-(-2)]
\\\\\\
y+2=\cfrac{7}{2}(x+2)\implies y+2=\cfrac{7}{2}x+7\implies y=\cfrac{7}{2}x+5$

grandymaker [24]

we are given

A woman walks due east on the deck of a ship at 4 mi/h.

the ship is moving south at a speed of 24 mi/h

so, firstly, we will draw diagram

so, we have

$OW=4$

$OS=24$

now, we can use Pythagoras theorem

$SW^2=OS^2+OW^2$

now, we can plug values

and we get

$SW^2=24^2+4^2$

$SW=24.33$

so,

the speed of the woman relative to the surface of the water is 24.33 mi/h .......Answer
