See a solution process below:

Substitute #color(red)(0)# for #color(red)(x)# in the equation. And, substitute #color(blue)(1)# for #color(blue)(y)# in the equation.

Then, evaluate the left side of the equation.

If the left and right side of the equation are equal the point in the problem is a solution for the equation.

If the left and right side of the equation are not equal the point in the problem is not a solution for the equation.

#color(blue)(y) + 4color(red)(x) - 1 = 0# becomes:

#color(blue)(1) + (4 * color(red)(0)) - 1 = 0#

#color(blue)(1) + 0 - 1 = 0#

#color(blue)(1) - 1 = 0#

#0 = 0#

Both sides of the equation are equal therefore #(0, 1)# is a solution for the equation in the problem.
