Do you want to graph this?




In order to graph this equation, we only need two points to create a straight line




--------------------------------Let's find the first point--------------------------------

y=x%2B2 Start with the given equation




y=%280%29%2B2 Plug in x=0 (you can start with any number, but zero is the easiest number to work with since anything multiplied by zero is zero)




y=0%2B2 Multiply 1 and 0 to get 0




y=2 Add



So when x=0, we have the value y=2. This means we have the first point




--------------------------------Let's find the second point--------------------------------

y=x%2B2 Start with the given equation




y=%281%29%2B2 Plug in x=1




y=1%2B2 Multiply 1 and 1 to get 1




y=3 Add



So when x=1, we have the value y=3. This means we have the second point




------------------------------------------------------------------------------------------------


So we have the two points: and


Now plot these two points on a coordinate system

Now draw a straight line through the two points. This line is the graph of y=x%2B2
