Linear Functions Writing

What is the equation of the line whose slope is -1 and whose y – intercept is -5?

Function 1 is represented by the table above:

Function 2 is represented by the equation y = 2x – 4.

Which statement is true?

• Function 1 has a greater rate of change than Function 2.

• Function 2 has a greater rate of change than Function 1.

• They have the same rate of change

• Function 1 has a positive rate of change, and Function 2 has a negative rate of change.

Find the slope of the line using the table.

The graph of a function is shown above. Which statement is true about a section of the graph?

• In Section N, the function is linear and decreasing.

• In Section P, the function is linear and increasing.

• In Section Q, the function in nonlinear and decreasing.

• In Section R, the function is nonlinear and increasing.

The table above shows the cost of different numbers of goldfish at a pet store.

• The cost increases $0.30 each time 1 goldfish is added.

• The cost increases $1.50 each time 1 goldfish is added.

• The cost increases $3.00 each time 5 goldfish are added.

• The cost increases $6.00 each time 5 goldfish are added.

Which graph represents a linear function?

•

• 

Write an equation of a line that passes through the point (-9,2) and is perpendicular to the line y = 3x - 12

• y = (-1/3)x - 1

• y = (1/3)x - 2

• y = -3x + 12

• y = 3x - 1

If two lines are parallel their slopes are  ____________

• the same.

• negative reciprocals of each other.

If two lines are perpendicular to each other their slopes are ____________

• the same.

• negative reciprocals of each other.

y = -2/3x + 2
y = 3/2x + 9
These lines are...

• Parallel

• Perpendicular

• Neither
