One of the lines below is vertical and therefore has undefined slope and y-iuntercept.

 [1] (value 10%) For the linear equation [ y = 6 - 3x ] The slope m = and the y-intercept is b =

 [2] (value 10%) For the linear equation [ 3y - 6x + 9 = 0 ] The slope m = and the y-intercept is b =

 [3] (value 10%) For the linear equation [ 3y + 9 = 0 ] The slope m = and the y-intercept is b =

 [4] (value 10%) For the linear equation [ 6x + 9 = 0 ] The slope m = and the y-intercept is b =

 [5] (value 10%) The line L passes through the point (3, 2) and is parallel to the line [ 3y - 6x + 9 = 0 ] The slope of L is m = and the y-intercept of L is b =

 [6] (value 10%) The line L passes through the point (3, 2) and is parallel to the line [ 3y - 6x + 9 = 0 ] An equation of the line L is [ y = x + ]

 [7] (value 10%) The line L passes through the points (1, 2) and (4, -1) An equation of the line L is [ y = x + ]

 [8] (value 10%) U-Haul charges \$30 per day and \$2 per mile to rent a truck. An equation for the total cost of renting this truck for x days across y miles is : C = x + y

 [9] (value 10%) (Linear Depreciation) An I-pad is worth \$500 new and \$260 in 12 months. An equation for the value V of this I-pad after x months is : V = x +

 [10] (value 10%) (Sales volume) The number N of books sold is 200 when the book price x is \$20, but this number N drops by 5 for each 50-cent increase in the book price. An equation relating N and x is : N = x +
