Chapter 4: Q. 128 (page 530)

Find an equation of a line containing the points(-4,4)androle="math" localid="1647334554418" (-4,3).

Short Answer

Expert verified

The equation of the line isx=-4.

Step by step solution

01

Step 1. Given Information

The points are:

(-4,4)and(-4,3).

02

Step 2. Finding the slope

The slope of the line:

m=y2-y1x2-x1

Inputting the values,

m=3-4-4-(-4)

=3-4-4+4=-10

The slope is undefined.

03

Step 3. Equation of a line.

The points have a common x-coordinate which is -4.

It is a vertical line.

The equation of the line isx=-4.
