Answer 1

$\displaystyle\huge\red{\underline{\underline{Solution}}}$

FORMULA TO BE IMPLEMENTED

1. GENERAL EQUATION OF ANY LINE IN SLOPE - INTERCEPT FORM

$y = mx + c$

Where

m = the slope of the line

c = y - intercept

2. If any curve / line passes through the origin ( 0, 0) then it satisfies the equation of the curve / line

TO JUSTIFY

Any equation in the form y = mx passes through origin

JUSTIFICATION

Here the general equation of any line in Slope - Intercept form is

$y = mx + c \: \: ....(1)$

Since it passes through the origin ( 0, 0)

So

$0 = 0 + c$

$\implies \: c = 0$

So Equation (1) reduces to

$y = mx$

Hence justified
