What is the slope intercept form of the function graphed below?
y = 1/3 x +2
y = - 1/3 x + 3
y = 2 x + 1/3
What is the y-intercept of the graph below?
b = 3
b = -3
b = 3/2
What is the y-intercept of the function that was used to generate the t-chart shown?
Hint: Y-intercept is the y value when x=0.
b = 3
b=4
b=2
What is the slope of the function that was used to generate the t-chart shown?
Hint: Slope is the m = change in y/change in x = ( y2-y1) / (x2-x1)

Given h(x) = 5 - 9x, find h(8).
Hint: Remember your order of operations.
h(8) = -360
h(8) = -67
Lee charges $3 for a basket and $2.50 for each pound of fruit picked at the orchard. Write an equation in y = mx + b form for the total cost of x pounds of fruit from the orchard.
y = 3x + 2.5
y = 2.50x + 3
y = 2.50x
y = 3x + 2.50
You plan to go snowboarding. The resort charges $15 an hour in addition to $25 to rent a board. Write an equation that represents the cost to go snowboarding for the day.
y=15x-25
15x+25y=100
25x+y=15
y=15x+25
Jerry has $20 and makes $7 per hour. Which equation represents the total amount of money Jerry has after working x hours?
y = 7x + 20
y = 7 + 20x
y = 20 + 7
Sandra has a $20 itunes gift card and spends $3 each month. Which equation can be used to find how much money Sandra has on her giftcard after x months?
y = 3x + 20
y = 3 + 20x
y = -3x + 20
y = -20x + 3

Bob's Plumbing charges $25 per hour plus a service fee of $40 for coming out to your house. Which equation models this situation?
y = 25x + 40
y = 40x + 25
y = 25x
y = 25x - 40
