To find the y-intercept, put x=0
y=2(0)1
y=1
To find the x-intercept, put y=0
2x1=0
2x=1
x=12
Draw a system of axis. Mark these points on the graph.
Now draw a line through these two ponts.
To draw the graph by used points,
let x=1, then y=2(1)1=21=3
Thus, first point is (1;3)
Let x=0, y=2(0)1=1
And second point is (0;1)
Let x=1, y=2(1)1=1
Third point is (1;1)
Here you go.

When the exponents of the variables are all 1,the equation is a line.Thus, it is enough to find two points to draw it.
We can calculate two points assigning a number to x and calculating the corresponding number for y.
For example, when x=0, y=2×01=1. And the line will pass through the point (0,1).
Now, we need a second point, we can take x=1, foe example, then y=2×11=1. This line passes through (1,1). Finally, we can mark the two points on the plane and draw the line passing from these points.

Plot the three points and draw a line through them. Add arrows to your line.
