Question 1133902


 given:

{{{ m=0}}} -> A horizontal line has a slope of zero.

equation is: {{{y=a}}}

if passes through ({{{0}}},{{{-1}}}) , => {{{a=-1}}}

so, your line is {{{y=-1}}}

or, you can do it as you already started:




{{{y-y[1]=m(x-x[1])}}}.........plug in given data:=>{{{m=0}}},{{{x[1]=0}}} and {{{y[1]=-1}}}

{{{y-(-1)=0(x-0)}}}

{{{y+1=0}}}

{{{y=-1}}}-> horizontal line
