Which line appears to have an x-intercept of 4 and a y-intercept of -2?
The graph of line k passes through (-4, 10) and (2, 8). Which equation describes a line parallel to line k that has a y-intercept at (0, -3)?
y=3x-3
y=-3x-3
y=1/3x-3
y=-1/3x-3
The table represents some points on the graph of a linear function. Which equation represents the same relationship.
y+32=10(x+5)
y+5=10(x+32)
y+32=1/10(x+5)
y+5=1/10(x+32)
The graph of a linear function is shown on the grid. (Note: There should be arrows.) Which equation is best represented by this graph?
y-2=4(x-1)
y-6=-4(x-2)
y-3=-4(x-10)
y+7=4(x+3)

What is the equation in standard form of the line that passes through the point ( 2, -4) and has a slope of -5?
5x+y=6
25x+5y=30
5x+y= -18
5x+y= -6
What are the equation and slope of the line shown on the grid? (Note: There should be arrows on the graph.)
x= -3; slope is undefined
x= -3; slope is zero
y= -3; slope is undefined
y= -3; slope is zero
What are the equation and slope of the line shown on the grid? (Note: There should be arrows on the graph.)
y=4; slope is zero
y=4; slope is undefined
x=4; slope is zero
x=4; slope is undefined
Rick prepares 7 kilograms of dough every hour he works at the bakery. The baker from the previous shift left 50 kilograms of dough in the refrigerator. Write an equation that models how much dough Rick has after x hours of work.
d(x)=50-7x
d(x)=50+7x
d(x)=7(x+50)
d(x)= -7(x+50)
The graph shown represents the number of tickets that a theater must sell in order to generate $350 in revenue from ticket sales. What statement best describes the x-intercept?
If the theater only sells children tickets, they must sell 140 in order to generate $350 in revenue.
The theater could sell 30 adult tickets and 80 children’s tickets to generate $350 in revenue.
If the theater only sells adult tickets, they must sell 70 in order to generate $350 in revenue
One adult ticket is twice as much as one children ticket.
You are visiting Baltimore, MD and a taxi company charges a flat fee of $3.00 for using the taxi and $0.75 per mile. What function can be used to find the price of your taxi ride after x miles?
p(x)=3 -0.75x
p(x)=0.75(x+3)
p(x)=3+0.75x
p(x)= -0.75(x+3)
