Q:

Billy graphed the system of linear equations to find an approximate solution. y = x + y = x – 3 Which points are possible approximations for this system? Check all that apply. (1.9, 2.5) (2.2, –1.4) (2.2, –1.35) (1.9, 2,2) (1.9, 1.5)

Accepted Solution

A:
Answer:[tex](2.2,-1.4)[/tex][tex](2.2,-1.35)[/tex]Step-by-step explanation:see the attached figure to better understand the problemwe know thatThe solution of the system of linear equations is equal to the intersection point both graphsIn this problemThe x-coordinate of the intersection point  belong to the interval[tex](2,3)[/tex]The y-coordinate of the intersection point  belong to the interval[tex](-2,-1)[/tex]the points that are possible  approximations for this system must be satisfy both intervalsPoint [tex](1.9,2.5)[/tex] -----> does not satisfy the interval of the x and y coordinatesPoint [tex](2.2,-1.4)[/tex] -----> is possible  approximation for this systemPoint [tex](2.2,-1.35)[/tex] -----> is possible  approximation for this systemPoint [tex](1.9,2.2)[/tex] -----> does not satisfy the interval of the x and y coordinates Point [tex](1.9,1.5)[/tex] -----> does not satisfy the interval of the x and y coordinates
