Select the correct point.One linear equation is defined by the points (2, 4) and (1, 1), while the other is defined by the points (2,-2) and (-1,-5). Which point representsthe solution to this system of equations?32-1-6-5-4-3-2-1123456-1-2-3-4-5-6

Respuesta :

The first linear equation passes through (2,4) and (1,1).

Using two point form the equation can be determined as,

[tex]\begin{gathered} \frac{y-1}{x-1}=\frac{4-1}{2-1} \\ \frac{y-1}{x-1}=\frac{3}{1} \\ y-1=3(x-1) \\ y-1=3x-3 \\ y=3x-2 \end{gathered}[/tex]

The second linear equation passes through (2,-2) and (-1,-5).

Using two point form the equation can be determined as,

[tex]\begin{gathered} \frac{y-(-2)}{x-2}=\frac{-5-(-2)}{-1-2} \\ \frac{y+2}{x-2}=\frac{-3}{-3} \\ \frac{y+2}{x-2}=1 \\ y+2=x-2 \\ y=x-4 \end{gathered}[/tex]

The system of equation can be solved graphically as,

Thus, (-1,-5) is the required solution.
