Using Algebra and Graphing with Quadrilaterals
MAFS.912.G-GPE.2.4 - Use coordinates to prove simple geometric theorems algebraically. For example,
prove or disprove that a figure defined by four given points in the coordinate plane is a rectangle; prove or
disprove that the point (1, V3) lies on the circle centered at the origin and containing the point (0,2).
1. The quadrilateral on a coordinate plane has the following characteristics.
can be represented by the equation where
can be represented by the equation where
Part 1: Graph the figure represented by the information given.
Part B: Describe the type of quadrilateral represented above.

it’s supposed to be -4+45=41

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
