Chapter 4 Review

An equation in the form y=mx+b is used for:
Writing a rule for any relationship
Writing a rule for linear relationship
Hacking math
Nothing
The value used to replace "m" in y=mx+b is called:
The unit rate
The growth rate
The growth per one unit
All of the above
The value use to replace the "b" in y=mx+b is called:
Y-intercept
Starting value
X-intercept
Figure number
What is the rule that represents the graph
Y=-3x+1
Y=7x-3
Y=-3x+7
Y=3x+7
Show how to use the rule y=4x + 3 to find x if y = 57.
Write the rule for the table above
Y = x + 3
Y = 4x +1
Y=3x+1
Y = 1+3x
Bryce has 43 miniature candy bars and he eats 3 candy bars each class period. Which rule best describes the relationship between the number of candy bars and the class period?
Y = 43 - 3x
Y = 3x+ 43
Y = 43x + 3
Y = -3x + 43
In the previous question x represents:
The number of class periods
The number of candy bars
43
The y-intercept
In the problem involving Bryce's candy bars, y represents
The number of class periods
The number of candy bars
43
The y-intercept
