Question

which is the equation of a line that has an x-intercept of -3 and is perpendicular to the line 2x-y=1? How do you solve it?

Answer 1

the given line slope is 2 , our line slope is perp on it then our line slope is -2

Answer 2

our line has x intercept at -3 then point (-3,0) lyes on it

Answer 3

what would the equation be?

Answer 4

equation should be y / (x+3) = -2

Answer 5

y = -2x-6

Answer 6

wait so how exactly did you get that?

Answer 7

i already said how i got it :)

Answer 8

fine

Answer 9

bnb is incorrect. if the slope of a given line is m, then the perpendicular to that line will have a slope -1/m

Answer 10

so the equation will be y/(x+3)=-1/2
and dat'll giv us 2y+x+3=0.

Answer 11

x+2y+6=0

Answer 12

ops my bad , thanx brackett

Answer 13
