Question

write the equation of the line that has a slope of -6 that passes through (7, 8).write the answer in slope-intercept form.

Answer 1

Use the formula:
\[y- y_1 = m(x-x_1)\]Where m = slope.
x1 = 7, y1 = 8.

Answer 2

\(\bf \begin{array}{lllll}
&x_1&y_1\\
% (a,b)
&({\color{red}{ 7}}\quad ,&{\color{blue}{ 8}})\quad

\end{array}
\\\quad \\
% slope = m
slope = {\color{green}{ m}}= -6

\\ \quad \\
% point-slope intercept
y-{\color{blue}{ y_1}}={\color{green}{ m}}(x-{\color{red}{ x_1}})\qquad \textit{plug in the values}\\
\qquad \uparrow\\
\textit{point-slope form}\)
