Question

I need help on sketching the graph

Answer 1

So the first thing to do is get two points. Lets start easy lets plug in 0 for x

`y = 2(0) + 1 \\ y = 1`
We get the point (0, 1).
Now plug in 2 for x

`y = 2(2)+ 1 \\ y = 5`
So the two points are (0, 1) and (2, 5)
Now from those two points draw a straight line
