Explanation:
the equation of a line in slope-intercept form is.
∙xy=mx+c
where m is the slope and c the y-intercept
rearrange 2x−y=1 into this form
y=2x−1
with slope =2 and y-intercept =−1
Plot the point (0,−1)
from this point move 2 units vertically and 1 unit to
the right
(0,−1)→(1,1)
repeat this from the point (1,1)
(0,−1)→(1,1)→(2,3)
Plot these points and draw a straight line through them
graph{(y-2x+1)((x-0)^2+(y+1)^2-0.04)((x-1)^2+(y-1)^2-0.04)((x-2)^2+(y-3)^2-0.04)=0 [-10, 10, -5, 5]}
