Answer:

using the intercepts of (1,0) and (-0.5,0)

Explanation:

substitute y=0.
x=1
Therefore (1,0) is the x-intercept of the equation

substitute x=0.
-2y=1
y=-0.5
Therefore (0,-0.5) is the y-intercept of the equation.

By plotting both points on the graph and linking them together, you have:
graph{x-2y=1 [-10, 10, -5, 5]}

with the two intercepts.
