Determine whether DFGH is a rectangle given each set of vertices. Justify your answer. 1) D (9,-1), F (9,5), G (-6, 5), H (-6,1). 2) D (6,2), F (8,-1), G (10,6), H (12,3).
3) D (-4,-3), F (-5,8), G (6,9), H (7,-2).

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
