Billy graphed the system of linear equations to find an approximate solution. y = A system of equations. y equals negative StartFraction 7 over 4 EndFraction x plus StartFraction 5 over 2 EndFraction. y equals StartFraction 3 over 4 EndFraction x minus 3.x + y = x – 3 A coordinate grid with 2 lines. The first line is labeled y equals negative StartFraction 7 over 4 EndFraction x plus StartFraction 5 over 2 EndFraction and passes through the (0, 2.5) and (2.2, negative 1.4). The second line is labeled y equals StartFraction 3 over 4 EndFraction x minus 3 and passes through (0, negative 3, 0.14) and (2.2, negative 1.4) Which points are possible approximations for this system? Select two options. (1.9, 2.5)

The points that are possible approximations on the graph are: (2.2, –1.4) (2.2, –1.35)

We have these equations

[tex]y = -\frac{7}{4} x+\frac{5}{2}[/tex]

[tex]y = \frac{3}{4} x-3[/tex]

From the picture we can see that these two lines intersected at a point on the graph.

This point of intersection is x, y.

The x coordinates are at 2, 3

The y coordinates are at -1, -2

From these points we can have approximations for this system as: (2.2, –1.4) (2.2, –1.35)
