Step-by-step explanation:
Hey there!
The equation of a st.line passing through point is;
(y + 6) = m1(x+3).........(i). [ Use one point formula]
y = -4x + 1............(ii)
Comparing 2nd equation with y = mx+c, we get;
Slope (m2) = -4.
For parallel lines;
[tex]m1 = m2[/tex]
(i.e m1=m2 = -4)
Putting value of slope in 1st equation,
[tex](y + 6) = - 4(x + 3)[/tex]
Smplify them to get equation.
[tex](y + 6) = - 4x - 12[/tex]
[tex]y = - 4x - 12 - 6[/tex]
[tex]y = - 4x - 18[/tex]
Therefore the required equation is y = -4x-18.
Hope it helps..
