which of the following is a point-slope equation of a line that passes through the points (10, 5) and (4, -7)
ivolga24 [154]

\bf (\stackrel{x_1}{10}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-7}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-7}-\stackrel{y1}{5}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{10}}}\implies \cfrac{-12}{-6}\implies 2 \\\\\\ \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-\stackrel{y_1}{5}=\stackrel{m}{2}(x-\stackrel{x_1}{10})

Can someone please help me with this? I'd greatly appreciate it! Serious answers only please!
vampirchik [111]
First find the slope:
The slopes of perpendicular lines must multiply to -1.
-9m = -1   ----> m = 1/9

Next, use point-slope form:
y - y1 = m(x-x1) ,   where given point (0,5) is (x1,y1)
y - 5 = (1/9)(x - 0)

Finally, solve for y to put it in slope-intercept form:
y = (1/9)x + 5
