One difference between linear inequalities and equations
"The signs used" or "inequalities flip when multiplied or divided by a negative number"
Three types of linear systems.
Parallel lines, the same line , intersecting lines
(One solution, No solution, Infinite solutions)
What is the distance formula?
sqrt((x2-x1)2+(y2-y1)2)
The solution to 2x + 1 >= 3 and 3x - 4 <= 17
1 <= x and x<= 7
Two ways the equation of a line can be written as
Slope-intercept form y = mx + b General (standard) form Ax + By = C
use the midpoint formula to find the midpoint between the points (-3,6) and (-5,4)
(-4,5)
The solution to 5x + 1 < 21 and 3x + 2 > -1
x > -1 and x < 4
Find the distance between the points (2,4) and (8,-4)
10 units
Use the distance formula to find the distance between the two points (-3,5) and (10,13). Round you answer to the hundredths place
15.26 units.
Given the end point (9,0) and the midpoint (3,4), find the missing endpoint.
(-3,8)
