Example Question #161 : How To Find Slope Of A Line

Given the following equation, , what is the slope of this line?

Possible Answers:

Correct answer:

Explanation:

The given equation is currently in standard form.  In order to find the slope, we will need to isolate the  variable and put the equation in slope-intercept form.

The slope-intercept form is:  

Subtract  from both sides.

Simplify both sides.

Multiply by four on both sides.

Distribute both sides.

Rearrange the terms.

The slope is:  

Example Question #321 : Equations Of Lines

What is the slope of the following set of coordinates?

 and 

Possible Answers:

Undefined

Correct answer:

Undefined

Explanation:

To solve this problem you need to know the slope formula and set it up accordingly:

 

This simplifies to:

  and because 0 is in the denominator this slope is undefined.
