Chapter 8.4, Problem 1WE

To determine

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

Answer to Problem 1WE

The slope of give line is $2$ and y-intercept is $1$ .

Explanation of Solution

Given information:

The equation $y=2x+1$ .

Formula used:

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

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

  $y=2x+1$

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

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

By comparing, we get

  $\begin{array}{l}m=2\\ c=1\end{array}$

The slope of give line is $2$ and y-intercept is $1$ .
