x y
1 2
2 5
6 2
4 9
5 1
Yes! Each input has one and only one output.
Evaluate y = 4x - 1 when x= -2
y = -9

A line has a slope of 1/3 and goes through the point (0, 8). What is the linear equation that represents this line?
The linear equation is y = (1/3)x +8
Mr. Harris attaches a small tank of propane to his portable grill. Then he turns on the grill and cooks food for a barbecue. Sketch a graph of the relationship between the amount of propane in the tank and time.
Decrease - straight line
Yes

No, it's a non-linear function!
An online clothing company sells custom sweatshirts. The company charges $6.50 for each sweatshirt and a flat fee of $3.99 for shipping. What linear equation represents this situation?
The linear equation is y = 6.5x + 3.99.
Liana hikes slowly away from her campsite for 30 minutes. Then she rests for 10 minutes. Finally, she hikes back at a faster pace, reaching her campsite in 20 minutes. Sketch a graph that could represent Liana’s distance from the campsite and time
Graph should include: Increase, constant, Decrease
Is it a function? {(2, 3), (4, 5), ( -2, 6), (-4, 5), (2, 7)}
NO, x repeats
Based on the function, what is y when x = -3?

y = -3
A table of values for a linear function is given. Fill in the missing value.
x 2 3 5
y 2 1 ?
y = -1
Re-write the equation into y=mx+b form:
y - 4 = -3(x - 3)
y = -3x + 13
he value of a stock decreases sharply for 2 weeks, increases sharply for 2 weeks, and then decreases sharply again for 2 weeks. Sketch a graph of the relationship between the value of the stock and time
Graph image should include: Decrease, increase, decrease, increase
Does the following table represent a function?
x y
1 2
2 5
6 2
2 9
5 1
No, because the input (x) of 2 has two different outputs (y)
A table of values for a linear function is given. Fill in the missing value.
x -1 0 1

y = -7
Does this graph represent a linear function?

Yes, it's a linear function!
What is the equation of this linear function? 
It is y = (-1/3)x + 5
A basketball player throws a ball upward from her hands, which are 5 feet above the ground. The basketball reaches a maximum height and then descends a few feet and becomes stuck in the net. Sketch a graph that could represent the relationship between the height of the ball and time.
Line starts above 0 and is an increase curve ending with a downward curve

Is this a function?
Yes!
