What is an equation of the line that passes through the points (4, -6)<br>and (8, -4)
QveST [7]

\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{-6})\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{-4}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-4}-\stackrel{y1}{(-6)}}}{\underset{run} {\underset{x_2}{8}-\underset{x_1}{4}}}\implies \cfrac{-4+6}{4}\implies \cfrac{2}{4}\implies \cfrac{1}{2}

\bf \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}{(-6)}=\stackrel{m}{\cfrac{1}{2}}(x-\stackrel{x_1}{4}) \\\\\\ y+6=\cfrac{1}{2}x-2\implies y=\cfrac{1}{2}x-8

QUICK HELP!!!!
sasho [114]

Answer:

y =  \frac{3}{4} x -  \frac{3}{2}

Step-by-step explanation:

y =  \frac{3}{4} x - 1→y - y1 = m( x - x1)

y - 6 =  \frac{3}{4} (x - 6)→y - 6 =  \frac{3}{4} x - 6

2(y - 6) = 2( \frac{3}{4} )(x - 6)

2y - 6=  \frac{3}{2}( x - 6)

2y - 6 =  \frac{3}{2} x - 9

- 6 \: from \: both \: sides

2y  =  \frac{3}{2} x - 3

divede \: by \: 2 \: on \: both \: sides

y =  \frac{3}{4} x -  \frac{3}{2}

Hope this helps!
