Grayson is designing a rectangular athletic field. on a scale drawing the vertex of the rectangle are (4, 5), (9, 10) ,and (9, 5). what are the coordinates of the fourth vertex?
a. (4, 9)
b. (4, 10)
c. (5, 10)
d. (5, 9)

Which equation could represent the relationship shown in the scatter plot? y=−3x−2 y=−3/4x+10 y=−2/3x+1 y=9x−12 scatter plot with x axis labeled variable x and y axis labeled variable y. points go from upper left to lower right.
