Example Question #151 : How To Find Slope Of A Line

Find the slope of the line if the line connects the points  and .

Possible Answers:

Correct answer:

Explanation:

Write the formula for the slope.

Substitute the points.

Reduce the fraction.

The slope is .

Example Question #3841 : Algebra 1

Find the slope of the following line:

Possible Answers:

Correct answer:

Explanation:

To find the slope of a line, we will write it in slope-intercept form

where m is the slope.  Given the line

we will need to solve for y, or get y to stand alone.  To do that, we will divide each term by 18.  So,

Using the information given above, we can see that the slope is -4.  

Example Question #315 : Equations Of Lines

What is the slope of the line ?

Possible Answers:

Correct answer:

Explanation:

To find the slope of the line, we will need to re-format the equation back to slope-intercept form, .

Add  on both sides.

Subtract  on both sides.

Simplify both sides.

This is a horizontal line and the value of  is zero.

The answer of the slope is:
