Finding x
2x = 10
x = 5
(1/2) + (4/2) = ?
5/2
Two lines that have the same slope and never intersect are...
Parallel
How far apart are points (2, 3) and (2, 5) on a graph?
2 units
This formula tells us how far apart two points are on a coordinate plane.
Distance Formula
3x-12 = 51
x = 21
(-2/3) + (4/3) = ?
2/3
Angles which sum to 180 degrees are...
Supplementary
How far apart are points (-1, 3) and (4, 3) on a graph?
5 units
This is the standard point-slope equation for a line.
mx + b = y
x2 + 4 = 29
x = 5 and x = -5
(1/6) + (2/12) = ?
1/3
Lines with opposite slopes are...
Perpendicular
Distance between (3, 2) and (1, 4)...
Square root of 8 units
This is how we find the hypotenuse of a triangle
Pythagorean Theorem
2x + 11 = -x - 4
x = -5
4/5 + 3/10 = ?
11/10
Angles on opposite sides of the transversal and outside the parallel lines are...
Alternate Exterior
Distance from (1, 6) to (-2, -3)...
Square root of 90.
This is the rule allowing us to add together pieces of a line to find the total length.
Segment Addition Postulate
3x2 = x2 + 18
x = 3 and x = -3
1/6 + 3/12 + 1/3 = ?
3/4

Postulate
Distance from (-1/2, 3) to (2, 4)
square root of 13/4 units
This formula finds us the center point on a line segment.
