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

Find the slope with the given equation.

Possible Answers:

Correct answer:

Explanation:

The equation of a slope is  is the slope while  is the intercept. We need to solve for 

 Subtract  on both sides. 

 Divide  on both sides.

So,  in this case is . The slope value will always be the coefficient of .

Example Question #152 : How To Find Slope Of A Line

Find the slope with the given equation.

Possible Answers:

Correct answer:

Explanation:

The equation of a slope is  is the slope while  is the intercept. So,  in this case is . The slope value will always be the coefficient of .

Example Question #153 : How To Find Slope Of A Line

Find the slope with the given equation.

Possible Answers:

Correct answer:

Explanation:

The equation of a slope is  is the slope while  is the intercept. Problem is we don't have a . This means the graph will be a vertical line with the line crossing through the axis at . Vertical slopes mean the slope is infinity.

 

Example Question #154 : How To Find Slope Of A Line

What is the slope of a line with the equation  ?

Possible Answers:

Correct answer:

Explanation:

The current equation is already in the slope intercept form.

The slope-intercept form is:

The  is the slope of the equation.

The answer is .

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 #151 : How To Find Slope Of A Line

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:
