STAAR Slope Questions

Two functions are given.  How does the graph of p compare to the graph of q?
HINT: Graph both equations on your calculator!

• The graph of p has a different y-intercept than the graph of q.
• The graph of p is less steep than the graph of q.
• The graph of p is steeper than the graph of q.
• The graph of p is parallel to the graph of q.

The slope of the line that passes through the points (-6,w) and (-10,4) is 1/8. What is the value of w?
HINT: :Label what is given and use the formula y-y1=m(x-x1).

• 36
• 34
• 9/2

The graph shows the time it took a worker to package 16 bottles of shampoo. The next day two workers packaged twice the number of bottles of shampoo in the same amount of time.
HINT: The rate INCREASED.

• The new graph has a y-intercept at 80.
• The new graph would be steeper.
• The new graph would be less steep.
• The new graph has a y-intercept at 8.

The population of Webb County, Texas, from the year 2000 through 2010 is shown in the graph. If the trend continues, what will be the population in 2015?
HINT: find the equation using LinReg!

• 307000
• 278500
• 471500
• 158000

Which table has the same rate of change of y with respect of x as y=4-(5/8)x?

Black ink: b(t)=152-33t  
Colored ink: c(t)=152-30t
describes the number of pages left to print after t minutes. Which is true?
HINT: the SLOPE changed from 33 to 30...which equation has a larger slope?

• The printer prints 3 more pages per minute in colored ink than in black ink.
• The printer prints 3 fewer pages per minute in colored ink than in black ink.
• The printer prints the same number of pages per minute in either type of ink.
• The printer prints the entire research report in 152 minutes.
