Write the equation in slope-intercept form:
2y + 4x = 12
y = -4x + 12
y = -4x + 6
y = -2x + 6
y = -2x + 4
Write the equation in slope-intercept form:
-3y + 5x = 12
y = 5x - 4
y = (5/3)x - 4
y = -(5/3)x + 4
y = 5x + 12
What are the units for the slope and y intercept in this relationship between velocity and time?
v (in m/s) = 0.5(?)t(in sec) + 0.2(?)
m/s2 ; m/s
m ; m/s
m/s ; s
m/s2 ; s
What is the best format for the mathematical model of this graph?
y = mx + b
y = -mx + b
y = -10 + 100
Power = -10 (units of power/years)time + 100 units of power

Which culture of bacteria had the highest frequency of growth? (growing the fastest)
Culture 1
Culture 2
Culture 3
None of the cultures had a frequency of growth
A student measured heights of each of 12 classmates. What are the proper labels for the axes of this graph?
x-axis = student and y-axis = height (cm)
x-axis = weight (g) and y-axis = height (cm)
x-axis = age (years) and y-axis = height (cm)
x-axis = height (cm) and y-axis = student
What can best be concluded from this data table?
Higher temperatures tend to increase the rate of plant growth.
Higher temperatures tend to decrease the rate of plant growth.
Lower temperatures stop all plant growth.
Lower temperatures tend to increase plant growth.
