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.

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.

graph{y=-2x+1 [-6.22, 6.267, -2.944, 3.29]}
