Chapter 12: Q.12.1 (page 680)

Is the following an example of a linear equation?

y=鈥�0.125鈥�3.5x

Short Answer

Expert verified

y=-0.125-3.5xis a linear equation.

Step by step solution

01

Given information

Given in the question that, We have to find that whether the following is an example of a linear equation

y=鈥�0.125鈥�3.5x

02

Explanation

The linear equation is an equation of two variables with one independent variable and one dependent variable. It has the below form:

y=a+bx

Here,

a-y-intercept

b-the slope

The variableyis the dependent variable and xis an independent variable.

The given equation is written below:

y=-0.125-3.5x

This above equation is of the same form as equation (1).

Here,a=-0.125 is the y-intercept and b=-3.5 is the slope. Hence, y=-0.125-3.5x is a linear equation.

Recently, the annual number of driver deaths per \(100,000\) for the selected age groups was as follows:

a. For each age group, pick the midpoint of the interval for the \(x\) value. (For the \(75+\) group, use \(80\).)

b. Using 鈥渁ges鈥� as the independent variable and 鈥淣umber of driver deaths per \(100,000\)鈥� as the dependent variable,

make a scatter plot of the data.

c. Calculate the least squares (best鈥揻it) line. Put the equation in the form of: \(\hat{y}=a+bx\)
