Answer:
y
=
m
x
+
b
m
 = slope
b
 = y-intercept (where the line crosses the x-axis)
go up to 
4
 on the 
y
 axis (4,0). That is one of the points. From that point, which is 
(
4
,
0
)
, use the slope and graph the next point, so the slope is 
m
, which is 
1
2
. The numerator ("
1
") states how much you go up or down (positive (+) up, negative (-) down). so in this case, you go up one on the y-axis. Then from that point go 
2
 points to the right (you get this from the denominator of 
1
2
) if there is no denominator (ex: y=5x+1), there is always a 
1
 underneath every number (
y
=
5
1
x
+
1
)
