Chapter 4.1, Problem 2E

To determine

To writing: and explain how can use slope-intercept form to write an equation of a line given its slope and y − intercept.

Answer to Problem 2E

Substitute the given value for the slope ( m ) and the y − intercept ( b ) in the slope-intercept form to get the equation of the line.

Explanation of Solution

Given information:

Formula Used:

The slope-intercept form of a line is:

  $y=mx+b$ .

Calculation:

Writing the equation of a line with its slope and y − intercept.

Step 1:

Write the slope-intercept form:

  $y=mx+b$ .

Step 2:

Substitute the given value for the slope ( m ) and the y − intercept ( b ) in the above form to get the equation of the line.
