Question 668952
1.  12x + y + 5 = 0
y = -12x - 5
slope is -12
y-intercept is -5
...
2. slope = {{{(-5--4)/(-6--2) = -1/-4 = 1/4}}}
y - -4 = {{{1/4}}}(x- -2)
y + 4 = {{{(1/4)(x+2)}}}
{{{y = (1/4)x + (1/4)(2) - 4}}}
{{{y = (1/4)x + (1/2) - 4}}}
{{{y = (1/4)x - 7/2}}}
...
3. slope = {{{(1-5)/(15--8) = -4/23}}}
...
4. slope = {{{(-5--8)/(-8--2) = 3/-6 = -1/2}}}
{{{-8 = (-1/2)-2 + b}}}
b = -8 - 1 = -9
{{{y = (-1/2)x - 9}}}

...
5.  slope?
y - 3 = m(x-5)
