List at least three shapes, other than hexagons, in the table. if the shape is a polygon, indicate whether the shape is regular or irregular. find the number of lines of reflection that will map each shape back on to itself when the shape flips about the reflection line. also describe the position of the line of reflection in your own words. use geogebra to guide you in this exercise, if you wish.

Step-by-step explanation:

A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Substitution can be used by substituting the value of one variable into the equation.

Because y=5x-7, we can substitute 5x-7 into y in -3x-2y=-12.

-3x-2(5x-7)=-12

-3x-10x+14=-12

-13x+14=-12

-13x+14-14=-12-14

-13x=-26

x=2

We now substitute x=2 into y=5x-7.

y=5(2)-7

y=10-7

y=3
