Question

True or false 2x+y=1 is the equation of a line passing through (-1, 3)

Answer 1

True substitute the values of x and y subsequently

Answer 2

it's true

the ans is true cuz

$2x + y = 1 \\ 2x = 1 - y \\ x = \frac{1 - y}{2}$

we can give the value y=3 so

$x = \frac{1 - 3}{2} = - 1$

so x=-1 y=3
