Question 880827
Plot the y-intercept (set x=0, plot (0,b)).
Pick another convenient x value. Plug it into the equation to generate y. Plot (x,y).
Draw the line that connects through these two points.
Example:
y=2x+1
x=0, y=1, (0,1)
When x=1, y=2+1=3 (1,3)

Example:
y=-(1/3)x+5
x=0, y=5, (0,5)
x=3, y=-1+5=4, (3,4)
