hugo is writing a coordinate proof to show that the midpoints of a quadrilateral are the vertices of a parallelogram. he starts by assigning coordinates to the vertices of quadrilateral rstv and labeling the midpoints of the sides of the quadrilateral as a, b, c, and d. quadrilateral r s t v in a coordinate plane with vertex r at 0 comma 0, vertex s in the first quadrant at 2 a comma 2b, vertex t also in the first quadrant at 2 c comma 2 d, and vertex v on the positive side of the x-axis at 2 c comma 0. point a is between points r and s, point b is between points s and t, point c is between points t and v, and point d is between points r and v. enter the answers, in simplified form, in the boxes to complete the proof. the coordinates of point a are ( , ). the coordinates of point b are ( , ). the coordinates of point c are (2c, d) . the coordinates of point d are (c, 0) . the slope of both ab and dc is . the slope of both ad and bc is −bc−a . because both pairs of opposite sides are parallel, quadrilateral abcd is a parallelogram.

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000
