Parallelogram abcd has vertices: a(-3,1), b(3, 3), c(4,0), and d(-2,-2). in two or more complete sentences, explain how you can use the coordinates of the vertices to prove that parallelogram abcd is a rectangle.

which expression represents the approximate length of bc?

step-by-step explanation:

me! what did you put for this question?

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
