Given two lines: 3x + y = 1 bx - y = 3 Which value of b makes the given lines parallel to each other? - 3 3 - 2

For lines to be parallel, their slopes should be equal. The equation to determine the slope of the line is - A/B where A and B are the numerical coefficients of terms with variables x and y, respectively.

-3/1 = - b/-1

The value of b from the equation is - 3.
