What is the point of intersection when the system of equations below is graphed on the coordinate plane?
(-x+y=4
16x+y=-3
A) (1.-3)
b ) -(1,3)
c) (1.3)
d) (-1, -3)

Respuesta :

Neither of the options are correct for the given equations.

Step-by-step explanation:

-x+y=4...................................................1

16x+y=-3...............................................2

Subtract equation 1 and 2

                              -x+y- 16x -y = 4+3

                               ⇒ -17x = 7

                               ⇒x= [tex]\frac{7}{-17\\}[/tex]

                              ⇒x= -0.4117

so,

                        16×-0.4417 + y = -3

                       ⇒y= -3+6.5872

                      ⇒y= 3.5872

So the point of intersection is (-0.4117, 3.5872)
