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

gregori [183]

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ -2}}\quad ,&{{ 2}})\quad 
% (c,d)
&({{ 0}}\quad ,&{{ 5}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{5-2}{0-(-2)}\implies \cfrac{5-2}{0+2}
\\\\\\
\cfrac{3}{2}$

$\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\implies y-2=\cfrac{3}{2}(x-(-2))\\
\left. \qquad \right. \uparrow\\
\textit{point-slope form}
\\\\\\
y-2=\cfrac{3}{2}(x+2)\implies y-2=\cfrac{3}{2}x+3\implies y=\cfrac{3}{2}x+3+2
\\\\\\
y=\cfrac{3}{2}x+5$

What is the length of CD in this diagram, ABC - EDC,

natima [27]

Answer:

Option A is the right option.

solution,

∆ABC~∆EDC

$\frac{bc}{cd} = \frac{ac}{ec} \\ \:$

putting the values,

$\frac{20 - x}{x} = \frac{20}{5} \\ or \: 5(20 - x) = 20x(cross \: multiplication) \\ or \: 100 - 5x = 20x \\ or \: - 5x - 20x = - 100 \\ or \: \: - 25x = - 100 \\ \: or \: x = \frac{ - 100}{ - 25} \\ x = 4$

Hope this helps..

Good luck on your assignment..
