You're almost there . . .
Two perpendicular lines intersect on the x-axis.
One line has equation:
What is the equation of the other line?
This is what i got to so far:
Slope of -1/2 reciprocated is just 2 . . . so we got: y = 2x + b
Then this is where i don't know where to go.
The line, has an x-intercept of 2.
. . Hence, the two lines intersect at (2,0).
You found that the other line has a slope of 2.
Can you write the equation of the line through (2,0) with slope 2 ?
