Write an equation for a line that is perpendicular to the line 8x-4y=12 and passes throught the origin
1 answer:
Answer:
y= -
x
Step-by-step explanation:
First, let's put the line in y=mx+b form
8x-4y=12
Subtract 8x over
-4y= -8x+12
Then divide everything by -4
y=2x-3
To find the perpendicular slope, negate the slope and flip the numerator and the denominator
Original Slope: 2/1
Flip: 1/2
Negate: -1/2
Then, use the point slop formula to find the equation of the line.
(y-
)=m(x-
)
Insert (0,0) in for
and -1/2 in for m
y-0= -1/2(x-0)
Distribute the -1/2
y-0= -1/2x+0
Add the 0 over
y= -1/2x
