Question

Find the equation of the line passing through points (5, 7) and (0, 2). Write the equation in slope-intercept form.

Answer 1

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&(5\quad ,&7)\quad &(0\quad ,&2)
\end{array}
\\\quad \\

slope = m= \cfrac{rise}{run} \implies \cfrac{y_2-y_1}{x_2-x_1}
\\ \quad \\

y-y_1=m(x-x_1)\qquad \textit{plug and chug}\)
