Question

write in standard form an equation of each line slope=-3 through (4,0)

Answer 1

Use the point slope formula

Answer 2

and then get it in this form: Ax + Bx = C

Answer 3

The point slope form: \[y-y_{1}=m(x-x_{1})\] so plug in what you have, m= -3 (slope) y1=0 and x1=4

Answer 4

\(\bf \begin{array}{lllll}
&x_1&y_1\\
&({\color{red}{ 4}}\quad ,&{\color{blue}{ 0}})\quad
\end{array}
\\\quad \\

slope = {\color{green}{ m}}= -3
\\ \quad \\

y-{\color{blue}{ y_1}}={\color{green}{ m}}(x-{\color{red}{ x_1}})\qquad \textit{plug in the values and move everything to the left}\\
\qquad \uparrow\\
\textit{point-slope form}\)
