Question

A line perpendicular to the straight line $y=2x-1$ is passing through $(0,4)$ , find the points of intersection of the line and $y=2x-1$.

• A. $(0,-1)$
• B. $(1,1)$
• C. $(2,3)$
• D. $(3,2)$

Answer 1

Answer: (C)

$(2,3)$

$y=2x-1$
line perpendicular to $y=2x-1$
slope of perpendicular line to the given line is = -1/2
equation of line : $y-4=-1/2(x-0)$
$x+2y-8=0$

intersection of $y=2x-1$ and

$x+2y-8=0$

is $(2,3)$
