Question 1086147

given:

point ({{{10}}},{{{-9}}}); 
slope {{{m = -2}}}

to find equation of the line, use slope-point form

{{{y-y[1]=m(x-x[1])}}}

{{{y-(-9)= -2(x-10)}}}

{{{y+9= -2x+20}}}

{{{y= -2x+20-9}}}

{{{y= -2x+11}}}


{{{drawing( 600, 600, -15, 15, -15, 15,
circle(10,-9,.12), locate(10,-9,p(10,-9)),
 graph( 600, 600, -15, 15, -15, 15,-2x+11)) }}}
