Question 318599
slope intercept form is {{{y=mx+b}}} where m=slope and b= intercept
you have the following:
{{{m=-8}}}
{{{x=-1}}}
{{{y=5}}}
substitute the letters for the numbers and solve for "b"
{{{y=mx+b}}}
{{{5=(-8)(-1)+b}}} multiply -8 and -1
{{{5=(8)+b}}} subtract 8
{{{-3=b}}}
<p>
rewrite equation
{{{y=mx+b}}}
{{{m=-8}}}
{{{-3=b}}}
{{{y=-8x-3}}}
