Question 308004
its in correct area
u need to know  the point slope formula and slope intercept formula.
point slope is {{{m=(y-y)/(x-x)}}}
slope intercept {{{y=mx+b}}}
(0,4)(7,-4)
{{{m=(4-(-4))/(0-7)}}}
{{{m=(8)/(-7)}}}
{{{m=-8/7}}}
{{{y=mx+b}}}
{{{4=m(0)+b}}}
{{{4=b}}}
{{{y=(-8/7)x+4}}}multiply by 7
{{{7y=-8x+28}}}
{{{7y+8x=28}}} this is your line
