Question

The perpedicular from the origin to the line y=mx+c meets it at point (-1,2).Find value of m and c.​

Answer 1

Answer:

m = 1/2 & c = 5/2

Step-by-step explanation:

Line passing through origin and point(-1,2) is ==> y= -2x

Since, Given line y= mx+c is perpendicular to y = -2x

So, m(-2) = -1 ==> m= 1/2. {If two lines are perpendicular then (m1)*(m2)= -1 }

Now, Line y= mx+ c passes through point(-1,2). So, put the value of x and y in the equation. You'll get ==> 2=(1/2)(-1) + c  ==> c= 5/2.
