Chapter 8.4, Problem 8OE

To determine

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

Answer to Problem 8OE

The slope of give line is $2$ and y-intercept is $7$ .

Explanation of Solution

Given information:

The equation $y-2x=7$ .

Formula used:

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

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

  $\begin{array}{l}y-2x=7\\ y=2x+7\end{array}$

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

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

By comparing, we get

  $\begin{array}{l}m=2\\ c=7\end{array}$

The slope of give line is $2$ and y-intercept is $7$ .
