in the coordinate plane , what are the two axes called

the x-axis and the y-axis 

100

what is a line segment 

a part of a line with two end points 

100

what is the distance between 0 and 5 in a number line 

5 units 

100

where would you pace the number three on a number line 

to the right of 0 three units away 

100

what is the midpoint segment

the point that divides the segment into two equal parts 

200

what are the coordinates of the origin on a coordinate plane 

(0,0)

200

how do you measure a length of a line segment?

use a ruler to calculate the distance between the two end points 

200

how do you calculate the distance between two points on a number line?

subtract the smaller number from the larger number    ( or use the absolute value of their difference)

200

if you have the numbers -2,0 and 5 which is located farthest to the right on a number line 

5

200

in geometry what is the perpendicular bisector of a line segment 

a line that divides a line segment into two equal parts at a 90 degree angle 

300

if a point is located at 4,-3 in which quadrant does it lie 

6

300

if a line segment has two endpoints at 2 and 8 on number line, what is its length?

6 units (|3-(-5)|=|3+5|=8

300

what is the diffrence between -3 and 7 on a number line?

10 units (|7-(-3)|=|7+3|=10)
300

on a number line where would you place the number -4

to the left of, four units away 

300

if the coordinates of the endpoints of a line segment are (2,3) and (6,7) what are the coordinates of th midpoint 

(4,5)

400

what is the name of the vertical line where x=0 is on the coordinate plane 

the y- axis

400

a line segment has endpoints at -5,1 and 3,1. what is the length of the segment? 

8 units (|3-(5)|=|3+5|=8)

400

two points on a number line are at -6 and 4. What is the distance between them? 

10 units (|4-(-6)=|4+6|=10)

400

what is the difference between-3 and 4 on a number line 

7 units (from -3 to 0 is 3 units and from 0 to 4 is 4 units, so 3+4=7)

400

if a point lies on the perpendicular bisector of a line sement, what is true about its distance from the two endpoints of the segment 

the point is equidistant from the two end points 

500
A  point is located at (-7,4). reflect this point across the y-axis. what are the new coordinates

7,4

500

the endpoints of a line segment are 1,2 and 4,6. using the distance formula what is the length of the segment 

5 units 

500

if point A ais at -8 and point B is at 3 and point C is ar th midpoint of A and B, what is the total distance from A to C and C to B? 

the total distance is 11 units. From A to C is 5.5 units (half) and C to B is also 5.5 units. total distance = 5.5+5.5=11

500

if point A is located at -5 and point B is located at 2 on a number line, what us the midpoint between A and B? 

the midpoint is calcuated by averaging the coordinates -5+2/2=-1.5

therefore the midpoint is -1.5

500
in a coordinate plane, if the endpoints of a line segment are A(1,2) and B(7,8), what is the equation of the perpendicular bisector of the segment? 

first, find the midpoint (4,5). the slope of AB is (8,-2) (7,1)=1. The slope of the perpendicular bisector is the negative reciprocal, so -1, Using point-slope form, the equation of the perpendicular bisector is y-5=-1(x-4) which simplifies to y=x+9
