Question 183029
Graph the equation and identify the y-intercept
y=x+3 
-------------------------
To graph the equation you need two points:
Let x = 0, then y = 3; point (0,3)
Let y = 0; then x = -3; point (-3,0)
-----------------
Plot the tow points and draw a line thru them.
The y-intercept is (0,3)
