Question

if the point (1,2) lies on the graph of 2x-y=m, then find the value of m

Answer 1

SOLUTION

GIVEN

The point (1,2) lies on the graph of 2x - y = m

TO DETERMINE

The value of m

EVALUATION

Here the given equation of the line is

2x - y = m

Now the given point (1,2) lies on the graph of 2x - y = m

So by the given condition

$\sf{(2 \times 1) - 2 = m}$

$\sf{ \implies \: 2 - 2 = m}$

$\sf{ \implies \: m = 0}$

FINAL ANSWER

Hence the required value of m = 0
