Question 1150299
A  line with a slope of -3/4 that passes through (12,-4)."
:
one way is to use the point slope form y - y1 = m(x- x1)
In this problem x1=12, y1=-4, m=-3/4
hence
y - (-4) = {{{-3/4}}}(x - 12)
 y1 becomes a +4; distribute the -3/4; becomes a +9
y + 4 = {{{-3/4}}}x + 9
y = {{{-3/4}}}x + 9 - 4
y = {{{-3/4}}}x + 5 is the equation for this line
;
looks like this
{{{ graph( 300, 200, -6, 15, -10, 10, -.75x+5) }}}
