Chapter 8.4, Problem 9WE

To determine

To find: Slope and y-intercept of each line.

Answer to Problem 9WE

The slope of give line is $1$ and y-intercept is $0$ .

Explanation of Solution

Given information:

The equation $y=x$ .

Formula used:

Slope-intercept line: $y=mx+c$ .

Where m is slope of line, and c is y-intercept of line.

  $\begin{array}{l}y=x\\ y=1x+0\end{array}$

Recall Slope-intercept line: $y=mx+c$ .

Where m is slope of line, and c is y-intercept of line.

By comparing, we get

  $\begin{array}{l}m=1\\ c=0\end{array}$

The slope of give line is $1$ and y-intercept is $0$ .
