Question

Consider the line that passes through the point (3, -6) and has a slope of 4.

Part 1: Write the equation of this line using point-slope form.
Part 2: Using your equation from part 1, rewrite this equation in slope-intercept form. Make sure to show all of your work.
Part 3: Using your equation from part 2, rewrite this equation in standard form. Make sure to show all of your work.

Answer 1

\(\bf \begin{array}{lllll}
&x_1&y_1\\
&(3\quad ,&-6)
\end{array}
\\\quad \\

slope = m= 4
\\ \quad \\

y-y_1=m(x-x_1)\qquad \textit{plug in your values }\)

Answer 2

\(\bf y-y_1=m(x-x_1)\) <-- point-slope form of an linear equation

to get the slope-intercept form, just solve for "y"
