Question

Find if the following points lie on the given line or not:

(iii)$(2,4)$ on the line $y=2x–1$​

Answer 1

NO
Step: Put $(2,4)$ in the equation of line​
Given Point:$(2,4)$
Line:$y=2x-1$

Put $x=2$ and $y=4$ in the given line equation,
$L.H.S:$
$y=4$
$R.H.S:$
$2x-1=2\left(2\right)-1=4-1=3$

$\therefore L.H.S.\ne R.H.S$

Hence the point $(2,4)$ does not lie on the line $y=2x-1$.
