Q. 5 A5.0( 2 Votes )

# Tathagata has written a linear equation in two variables x + y = 5. I write another linear equation in two variables, so that, the graphs of two equations will beparallel to each other

x + y = 5 …(1)

Let us express the equations (1) in the form of

a1x + b1y + c1 = 0 where a and b can’t be 0 at the same time.

Let the required equation be a2x + b2y + c2 = 0

x + y = 5

x + y + (-5) = 0

Or 1 × x + 1 × y + (-5) = 0

Here a1 = 1, b1 = 1, c1 = -5

For lines of equation to be parallel in the graph, we need Let and where k1 and k2 are any real number and k1≠k2 also both are non zero.

For simplicity, take k1 = 0.5 and k2 = 0.2

So, , and Therefore, required equation is 2x + 2y – 25 = 0 which will be parallel in the graph with equation x + y = 5
