You can set both equations together

y = -3x + 1

and y = x - 3

we can replace the y of one equation with the other side 

-3x+1 = x-3

add 3x on both sides

1 = x + 3x -3
add 3 on both sides

1 + 3 = x+ 3x

simplify

4 = 4x

divide by 4 on both sides

x = 1

y = x - 3
y = 1 - 3
y = 2

So the solution is: (1,2)

x | - 8 - 4 0 4 8

y | 28 16 4 - 8 - 20

to calculate the values of y, substitute the given values of x into the equation

x = - 8 : y = (- 3 × - 8 ) + 4 = 24 + 4 = 28

x = - 4 : y = (- 3 × - 4 )+ 4 = 12 + 4 = 16

x = 0 : y = (- 3 × 0 ) + 4

0 + 4 = 4

x = 4 : y = (- 3 × 4 ) + 4 = - 12 + 4 = - 8

x = 8 : y = (- 3 × 8 ) + 4 = - 24 + 4 = - 20
