Chapter 2: Problem 86

Explain how to use the general form of a line's equation to find the line's slope and \(y\) -intercept.

Short Answer

Expert verified
The slope \(m\) and the \(y\)-intercept \(c\) can be identified directly from the general form of a line's equation \(y = mx + c\). \(m\) is the coefficient of \(x\) and represents the slope, while \(c\) is the constant term and represents the \(y\)-intercept.

Step by step solution

01

Identify The General Form

The general form of a line's equation is given as \(y = mx + c\). It's crucial to be able to identify this form in any equation given.
02

Identify The Slope

The coefficient of \(x\) in our equation, \(m\), represents the slope of the line. The slope tells us the steepness of the line, including if the line is ascending (positive slope) or descending (negative slope).
03

Identify The y-intercept

The constant term in our equation \(c\) is the \(y\)-intercept. It represents the point where the line crosses the \(y\)-axis. The \(y\)-intercept indicates the value of \(y\) when \(x = 0\).

You will be developing functions that model given conditions. A chemist working on a flu vaccine needs to mix a \(10 \%\) sodium-iodine solution with a \(60 \%\) sodium-iodine solution to obtain a 50 -milliliter mixture. Write the amount of sodium iodine in the mixture, \(S,\) in milliliters, as a function of the number of milliliters of the \(10 \%\) solution used. Then find and interpret \(S(30)\)

Evaluate each piecewise function at the given values of the independent variable. $$h(x)=\left\\{\begin{array}{cl}\frac{x^{2}-9}{x-3} & \text { if } x \neq 3 \\\ 6 & \text { if } x=3\end{array}\right.$$ a. \(h(5)\) b. \(h(0)\) c. \(h(3)\)

In Exercises, if \(f(x)=\) int \((x),\) find each function value. $$f(1.06)$$

a. Use a graphing utility to graph \(f(x)=x^{2}+1\) b. Graph \(f(x)=x^{2}+1, g(x)=f(2 x), h(x)=f(3 x)\) and \(k(x)=f(4 x)\) in the same viewing rectangle. c. Describe the relationship among the graphs of \(f, g, h\) and \(k,\) with emphasis on different values of \(x\) for points on all four graphs that give the same \(y\) -coordinate. d. Generalize by describing the relationship between the graph of \(f\) and the graph of \(g,\) where \(g(x)=f(c x)\) for \(c>1\) e. Try out your generalization by sketching the graphs of \(f(c x)\) for \(c=1, c=2, c=3,\) and \(c=4\) for a function of your choice.

You will be developing functions that model given conditions. You commute to work a distance of 40 miles and return on the same route at the end of the day. Your average rate on the return trip is 30 miles per hour faster than your average rate on the outgoing trip. Write the total time, \(T,\) in hours, devoted to your outgoing and return trips as a function of your rate on the outgoing trip. Then find and interpret \(T(30) .\) Hint: Time traveled \(=\frac{\text { Distance traveled }}{\text { Rate of travel }}\)
