Question

Find the equation of the line containing the point P and having the slope m. Write your answer in slope-intercept form. Graph this line and submit the graph to the Dropbox. Please be sure to show all of your work.

P = (-4, -6), m = 3

Answer 1

\[\Large \begin{array}{l}
P = ( - 4, - 6)\\
m = 3\\
y = mx + c\\
- 6 = 3( - 4) + c\\
- 6 = - 12 + c\\
c = 6\\
y = 3x + 6
\end{array}\]

Answer 2

use the point gradient formula \[y - y _{1} = m(x - x _{1})\]

from your information \[y _{1} = -6 x _{1} = - 4\]

then
\[y - (-6) = 3(x - (-4))\]

simplify and put in the form... y = mx + b

Answer 3

Thank you both for the help.
