Question

draw the situation in which the equation of a line passing through the origin if Y= MN
and C=O

Answer 1

Answer:

Step-by-step explanation:

We shall first suppose the straight line not parallel to

either axis.

Let ABD he a straight line meeting the axis of y at B.

Draw a straight line OE through the origin parallel to ABD.

In ABD take any point P ; draw PM parallel to 0 Y, meeting OX at M, and OE at Qm

Suppose OB=c, and the tangent of EOX = m; and let

x, y be the co-ordinates of P ; then

y = PM = PQ+QM = 0B+ QM

= c + OMtan QOM=c + mx.

Hence the required equation is

y = mx + c.

OB is called the intercept on the axis of y; if the straight

line crosses the axis of y on the negativ
