graph each linear equation in two variable. Find at least five solutions in your table of values for each equation. y = 1/3x -1 and y=-5/2x +1

graph each linear equation in two variable. Find at least five solutions in your table of values for each equation. y = 1/3x -1 and  y=-5/2x +1
Answer :- 
In first equation  y  = 1/3x -1 the cofficient of x is 1/3 
so plug the value multiply of 3 so plug x = 0,-3,+3,-6,+6 we get 

x (x/3) -1      
0 -1
-3 -2
3 0
-6 -3
6 1


in second equation  y=-5/2x + 1 the cofficient of x is -5/2 here 2 is in denominator 
so plug the value x multiple of 2 so plug x = 0 ,-2 ,  2,  4, -4 

x (-5/2)*x +1
0 1
2 -4
-2 6
4 -9
-4 11


now use these values to draw the graph
