Now plot the graph with these two points: linear graph cutting x-axis at 0.5 and y-axis at 1 as shown in the attached graph.

Explanation:

This is a linear equation and will have a linear graph of straight line.

The easier way to plot a linear graph is to find the x and y intercepts of the given equation.

y=-2x+1

Find the the x intercept by putting y=0

0=-2x+1

2x=1

x=1/2

So, x intercept is (0.5,0)

Find the y intercept by putting x=0

y=-2(0) + 1

y=1

So, y intercept is (0,1)

Now plot the graph with these two points: linear graph cutting x-axis at 0.5 and y-axis at 1 as shown in the attached graph.
