Find the zero of the function \(f\) $$f(x)=-2 x$$

Give the (a) \(x\) -intercept, (b) \(y\) -intercept, (c) domain, (d) range, and (e) slope of the line. Do not use a calculator. $$f(x)=\frac{2}{3} x-2$$

Write the slope-intercept form of the line that passes through the given point with slope \(m .\) Do not use a calculator. Through \((-8,1), m=-0.5\)

Classify each number as one or more of the following: natural number, integer, rational number, or real number. \(16,351,000,000,000\) (The federal debt in dollars in January 2013 )

Using interval notation, write each set. Then graph it on a number line. $$\\{x | 1 \leq x<2\\}$$

Give the (a) \(x\) -intercept, (b) \(y\) -intercept, (c) domain, (d) range, and (e) slope of the line. Do not use a calculator. $$f(x)=-\frac{2}{5} x+2$$

$$\text { Work Exercises } 1-6 \text { mentally. Do not use a calculator.}$$ Consider the following problem. One number is three less than six times a second number. Their sum is \(32 .\) Find the numbers. If \(x\) represents the second number, which equation is correct for solving this problem? A. \(32-(x+3)=6 x\) B. \((3-6 x)+x=32\) C. \(32-(3-6 x)=x\) D. \((6 x-3)+x=32\)
