Solve the system of equations by graphing.

[tex] -\frac{1}{3}x + y=-1 \ and \ y=4+\frac{1}{3}x[/tex]

We solve first equation for y

[tex]-\frac{1}{3}x + y=-1[/tex]

[tex]y= \frac{1}{3}x - 1 [/tex]

We make a table for each equation and then we graph it

x -----> [tex]y= \frac{1}{3}x - 1[/tex]

-3 -----> -2

0 -------> -1

3 -------> 0

Table for second equation

x -----> [tex]y=4+\frac{1}{3}x[/tex]

-3 -----> 3

0 -------> 4

3 -------> 5

Plot all the points on the grid and make a line

The graph is attached below.

Two lines are parallel to each other. So, no solution for system of equations.
