Parallelogram- two lines that have the same angle and are 180 degrees parallel to each other.

Square- Four angles that are 90 degrees.
Finding Inverse of matrix- first, find the detergent and put 1 over the total.
Additive identity- use [0,0,0,0] and multiply with the equation.
multiplicative identity- use [1,0,0,1] and multiply with the given equation.
Matrix equation- use [a,b,c,d ]*[x,y] = [e,f]
Transformation matrices- use [1,0,0,-1] and multiply to the equation and the shape will reflect over the x axis.

2a+3b=-2
2c+3D=3
Note:To find the detergent you multiply a*d-b*c
Explain: first find the detergent which is found by using the formula. Then Solve the problem and put it in matrix format.

2.(1,0,0,1)*(2,5,6,3,7,4)
Answer is ((2,5,6,-3,-7,-4)]]> 2017-03-17 15:45:55 UTC https://padlet.com/wangc0832/8lrrnsgokfah/wish/160832177 Formula wangc0832 https://padlet.com/wangc0832/8lrrnsgokfah/wish/160834168 1. Root x2-X1-y2-y1
Similar equation to y2-y1/x2-x1
