Answer:
line r: y=-2x-2
line s: -2x+1
lime t: -2x+3
Step-by-step explanation:
every slope must be -2 since that's stated in the question
to find b in y=mx+b, you substitute 0 for x and the y coordinate when x is 0 into the equation (for example for slope r, when x is 0 then y is -2, so -2=-2(0)+b) then solve for b (-2=-2(0)+b is -2=b)
basically, b is the y component when x is 0
You have to be able to know the appropriate properties or postulates to apply on the angles or segments to simplify them. An example would be the Angle Addition Postulate. This postulates states that the sum of the individual measures of the interior angles is equal to the measure of the included angle. There are still a lot more properties to choose from depending on the situation.
C. polygons!!
the polygons it is made of are called faces. the edges of the faces are called the edges of the polyhedron
