$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\
&(4\quad ,&2)\quad &(3\quad ,&1)
\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 in your values and solve for "y"}$

wat that mean

jdoe0001 · Answer

2 points, find the slope with those 2 points
once that's found, plug your values in the point-slope form of $\bf y-y_1=m(x-x_1)$ and solve for "y" to get the equation
