Question

Use graph paper for this question. Take $2cm=1$ unit on both the axes. Draw the graph of $x+y+3=0$ and $3x-2y+4=0$. Measure and record the distance of the point of intersection of the lines from the origin in cm.

Answer 1

Plotting the graph of given equation and hence finding the point of intersection,

$P=(-2,-1)$

$OP$=$\sqrt{2^2+1^2}=5\times 2=10cm$

(since $\perp$ unit = 2 CM)
