Question

Which of the following linear equations has its graph passing through origin a)y=2 b)x+y=1 c)y=2x+1 d) y=0.2x

Answer 1

Answer:

y=0.2x

Step-by-step explanation:

We know, origin has coordinates (0,0)

Putting x=0 satisfies the equation

So LHS=RHS

So y=0.2x passes through origin

Answer 2

Answer:

d) y= 0.2x

Step-by-step explanation:

Any line which is passing through the origin has y intercept = 0.

So , only in option d , term of y intercept is missing.

It means , y = mx+c , where c is y intercept has value of c = 0 ,so it passes though origin.
