Make a number table with these two equations ( use numbers that i can put into a graph easily)
1.y = -4/3x - 1
2.y = x + 3

Input numbers for x and evaulate to get y values

if the slope is a/b, try inputing numbers that are multipules of b so you don't get fraction points
try 0 for x first

for first equation
3 is bottom number so try multipules of 3
if x=0, y=-1
(x,y)
(0,-1)
(3,-5)
(6,-9)
(-3,3)
(-6,7)

for second equation
bottom number is also 3 so try multipules of 3
(0,3)
(3,4)
(6,5)
(-3,2)
(-6,1)
