Question

write the equation of a line given the points (1,1) (4,16)

Answer 1

do you know how to find slope?

Answer 2

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&(1\quad ,&1)\quad &(4\quad ,&16)
\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)\quad \textit{plug in your values and solve for "y"}\)
