Q1.

Describe all numbers x that are at a distance of 3 from the number 6. Express this using absolute value notation.

Q2.

Find the x- and y-intercepts of the graph of the function f(x)=−4|x−3|+8.

Enter your answers as points, (a,b).

Q3.

In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%).

Q4.

Students who score within 11 points of the number 90 will pass a particular test. Write this statement using absolute value notation and use the variable x for the score.

Q5.

Determine whether the function is increasing or decreasing.

b(x)=9−4x

Q6.

Find the slope of the line that passes through the two given points.

(−5,4) and (3,6)

Q7.

Find a linear equation satisfying the condition, if possible.

Passes through (−3,6) and (−1,14) 

Q8.

Find the x- and y-intercepts of the equation.

h(x)=2x−5

Enter your answer as points (a,b). 

Q9.

Use the description of the pair of lines given below to find the slopes of Line 1 and Line 2. 

Line 1: Passes through (0,5) and (3,−25)

Line 2: Passes through (−1,−3) and (3,37)

Q10.

Write an equation for the line graphed below

Q11.

Sketch the graph of the equation g(x)=−3x+2.

You can refer to Participation Activities 6 and 7 in the Reading and Participation section "Linear Functions". Those two activities can give you practice in drawing graphs of lines in Mobius.

Q12.

A clothing business finds there is a linear relationship between the number of shirts, n, it can sell and the price, p, it can charge per shirt. In particular, historical data shows that 1,000 shirts can be sold at a price of $30, while 3,000 shirts can be sold at a price of $14. Find a linear equation in the form p(n)=mn+b that gives the price p they can charge for n shirts.

Q13.

A farmer finds there is a linear relationship between the number of bean stalks, n, she plants and the yield, y, each plant produces. When she plants 30 stalks, each plant yields 29 oz of beans. When she plants 32 stalks, each plant produces 28 oz of beans. Find a linear relationship in the form y=mn+b that gives the yield when n stalks are planted.

Q14

Q15.

Find one possible missing coordinate so that the point becomes a solution to the given inequality.

(x,3)  is a solution to  4x−1>y.

x=  

Q16.

Sketch the graph of the inequality below.

y>4x+3

You can refer to Participation Activities 11 and 12 in the Reading and Participation section Graphing Linear Inequalities. Those two activities can give you practice in drawing graphs of linear inequalities in Mobius.
