Example Questions

Example Question #2 : Use Similar Triangles To Show Equal Slopes: Ccss.Math.Content.8.Ee.B.6

Give the -intercept, if there is one, of the graph of the equation

Possible Answers:

The graph has no -intercept.

Correct answer:

The graph has no -intercept.

Explanation:

The -intercept is the point at which the graph crosses the -axis; at this point, the -coordinate is 0, so substitute  for  in the equation:

However, since this expression has 0 in a denominator, it is of undefined value. This means that there is no value of  paired with -coordinate 0, and, subsequently, the graph of the equation has no -intercept.

Example Question #301 : Geometry

Give the -intercept, if there is one, of the graph of the equation

Possible Answers:

The graph has no -intercept.

Correct answer:

Explanation:

The -intercept is the point at which the graph crosses the -axis; at this point, the -coordinate is 0, so substitute  for  in the equation:

The -intercept is .

Example Question #3 : Use Similar Triangles To Show Equal Slopes: Ccss.Math.Content.8.Ee.B.6

Give the -intercept, if there is one, of the graph of the equation

.

Possible Answers:

The graph does not have a -intercept.

Correct answer:

Explanation:

The -intercept is the point at which the graph crosses the -axis; at this point, the -coordinate is 0, so substitute  for  in the equation:

The -intercept is the point

Example Question #1 : How To Find A Line On A Coordinate Plane

Give the slope of the line that passes through  and .

Example Question #2 : How To Find A Line On A Coordinate Plane

What is the slope of the line that passes through and ?

Possible Answers:

Correct answer:

Explanation:

We can use the slope formula:

 

Example Question #3 : How To Find A Line On A Coordinate Plane

What is the slope of the line that passes through  and ?

Possible Answers:

Correct answer:

Explanation:

We can use the slope formula:

 

Example Question #301 : Geometry

What is the slope given the points  and ?

Possible Answers:

Correct answer:

Explanation:

Write the slope equation, substitute the point values, and solve for the slope.

Example Question #1492 : Concepts

A point  is shifted  to the left and  down. What is the new point?

Possible Answers:

Correct answer:

Explanation:

A point is defined as . If the point is shifted left or right, the  value will be added or subtracted. If the point is shifted up or down, then the  value will be added or subtracted.

3 units to the left is: 

5 units down is: 

The new point is: 

Example Question #1491 : Concepts

Shift  up  and left .  State the new point.

Possible Answers:

Correct answer:

Explanation:

The movement of a point left and right will change the x-value of the point, as movement up and down will change the y-value of the point.

Three units up is adding three to the y-value.

Left three units is subtracting three from the x-value.

The point is:  

Example Question #2084 : Hspt Mathematics

Begin at the point  on the coordinate plane and move six units to the left. Where are you now?

Possible Answers:

Correct answer:

Explanation:

Moving six units to the left changes the -coordinate of the point by subtracting six from it, while preserving the -coordinate. The ordered pair of the new location is , or .
