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

[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 +
