Chapter 4.5, Problem 40MR

To determine

To graph: The equation $y=4x-1$ on the graph paper.

Explanation of Solution

Given:

The equation is $y=4x-1$ .

Calculation:

Substitute $x=0$ in the given equation to obtain the value of $y$ as follows:

  $\begin{array}{c}y=4\left(0\right)-1\\ =0-1\\ =-1\end{array}$

Substitute $x=1$ in the given equation to obtain the value of $y$ as follows:

  $\begin{array}{c}y=4\left(1\right)-1\\ =4-1\\ =3\end{array}$

Substitute $x=2$ in the given equation to obtain the value of $y$ as follows:

  $\begin{array}{c}y=4\left(2\right)-1\\ =8-1\\ =7\end{array}$

Substitute the obtained values in the table given below.

$x$	$y$
0	$-1$
1	3
2	7

Plot the points and join them to obtain the graph as follows:
