Find the equation of the line that contains the point (1,-2)

Question

parallel is one answer

and perpendicular is another

i also have to find the equation of a line that contains points (1,-2)

i have to graph all 3 on a cartisian plane

Answer 1

yukan hav infinite lines thru 1 point...chuez yer slope

yer point=(1,-2)

y=slope*x+konstant or  y=mx+k

wen x=1, we want y=-2

m*1+k=-2

so...m=-k-2  or   k=-2-m, take yer pik
