Assessment 1: Graph Analysis

Consider the graph below. Part A Find the y-intercept and slope of the line. Fill in the blanks in the statement.

According to the table, what is the Fahrenheit equivalent of -15 degrees Celsius?

(a)  

Part A: According to the table, what is the Celsius equivalent of 32 degrees Fahrenheit?

• 0

• 32

• -10

• 100

Based on the graph, do the points from the table lie on a straight line?

• True

• False

Is the function F = (9/5)C + 32 a linear function?

• True

• False

F = (9/5)C + 32 is a linear function because:

• It forms a straight line when graphed and has a constant rate of change.

• It forms a curve when graphed and the rate of change varies.

• It does not have a constant rate of change.

• It is not related to temperature conversions.

Consider the equation below. (3/4)(24 - 16x) = -(2/3)(18x - 27) How many solutions does the equation have?

• one, x = 0

• one, x = -27/8

• no solutions

• infinitely many solutions

In the equations 6x - 12y = a and 3x - 6y = b, a and b are constants. The two equations have infinitely many solutions. Which statements are true? Mark all that apply.

• If a = 5, b = 10.

• If a = 18, b = 9.

• If a = 8, b = 4.

• If a = 14, b = 28.

• $154 would have been collected for student tickets.

• $134 would have been collected for student tickets.

• $980 would have been collected for adult tickets.

• $1,050 would have been collected for adult tickets.

• The total ticket sales would have been $1,204.

The function F = (9/5)C + 32 gives the temperature in degrees Fahrenheit, F, based on the temperature in degrees Celsius, C. Degrees Celsius, C: -15, -10, -5, 0, 5, 10, 15 Degrees Fahrenheit, F: __, __, __, __, __, __, __

• 5, 14, 23, 32, 41, 50, 59

• -5, 0, 5, 10, 15, 20, 25

• -10, 0, 10, 20, 30, 40, 50

• -15, -10, -5, 0, 5, 10, 15
