Question

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

Answer 1

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. 

Answer 2

Answer:

-3

Step-by-step explanation:

When you graph both equations, these are parallel.  Verified by Odyssey ware
