use graph paper and a straightedge to draw the figure. the set of points (2, 4), (5, 8), (11, 8), and (8, 4) identifies the vertices of a quadrilateral. which is the most specific description to tell which figure the points form? a. parallelogram b. square c. rectangle d. rhombus

Parallelogram

Step-by-step explanation:

graphing them makes two sets of parallel lines

idk this answer sorry cant on this one.

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
