Write the relation as a set of ordered pairs. On a coordinate plane, points are at (negative 2, negative 1), (0, 1), (2, 3). a. ordered pairs: {(–1, –2), (0, 1), (3, 2)} b. ordered pairs: {(–2, –1), (1, 0), (3, 2)} c. ordered pairs: {(–2, –1), (0, 1), (2, 3)} d. ordered pairs: {(–1, –2), (1, 0), (2, 3)} Please select the best answer from the choices provided

The correct option is;

c.  {(-2, -1), (0, 1), (2, 3)}

Step-by-step explanation:

Given that the points are on a coordinate plane, we have the ordered pair given by the pair that follows a set of rules

In the question, the most appropriate set of coordinates that form an ordered pair are {(-2, -1), (0, 1), (2, 3)}

Each of the x-coordinate term is less than the y-coordinate term by 1, also the points are colinear as the slope between the points (-2, -1) and (0, 1) is the same as the slope between the points (-2, -1) and (2, 3).

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
