Uh I thought slope is y=mx+b..
Answer:
-1
Step-by-step explanation:
-40/7+8-23/7
= -40/7+8-23/7
= 16/7-23/7
= -1
Answer:
There are a number of ways to show whether a quadrilateral placed on a coordinate plane is a parallelogram or not. Here are a few ways:
1. Show that both pairs of opposite sides are congruent.
2. Show that both pairs of opposite sides are parallel
3. Show that a pair of opposite sides are congruent and parallel
4. Show that the diagonals bisect each other.
In this activity, we will use the Distance, Midpoint and Slope Formulas that we learned in Algebra 1 to show congruent, bisected and parallel segments.

The midpoint of a segment in the coordinate plane with endpoints
Step-by-step explanation:
Use the formula for area of a triangle:
Area = 1/2 x base x height.
Fill in what you know:
40 = 1/2 x 20 x height
Multiply both sides by 2:
80 = 20 x height
Divide both sides by 20
Height = 4 m
Answer:
286.94 cm
Step-by-step explanation:
Data:
Area = 8,607
b1 = 105
b2 = 123
Area = 1/2 * (b1 + b2) * h
h = 2 * Area/b1 + b2
h = 2 * 8,607/105 + 123
h = 286.94 cm
I'm not sure if it's right but that's what my calculator gave me.
