Question 22033
Just take the x values and do what they do in that Glade commercial:  "PLUG IT IN, PLUG IT IN!!"


A. 
y = 4x + 8
x y 
-3| 4(-3) +8= -12 +8=-4
-2| 4(-2) +8 =-8 +8 = 0
-1| 4(-1) + 8= =4 + 8 = 4
0 | 4(0) + 8 = 8
{{{ graph(300,300,-6,4,-10,10,4x+8)}}}

You do the next one, I'll draw the graphs:

B. 
y = x + 4
x y 
0 
1 
2 
3 
{{{ graph(300,300,-10,10,-10,10,x+4)}}}
