Question

PLEASE HELP!

What is the equation of the following line written in general form? (The y-intercept is -1.)



2x + y - 1 = 0

-2x - y - 1 = 0

2x - y - 1 = 0

Answer 1

The correct answer is 2x - y - 1 = 0

To find this, use the ordered pair (1, 1) in any of the equations. If it results in a true statement then this can be an equation.

2x - y - 1 = 0

2(1) - (1) - 1 = 0

2 - 1 - 1 = 0

0 = 0 (TRUE STATEMENT)
