Given Line Eqn ---- > 2x + y =-11

We know a line passes thru the x & y axis called the intercepts.

For x -Intercept, let fy=0:
2x%2B0=-11
cross%282%29x%2Fcross%282%29=-11%2F2
red%28x=-11%2F2%29

For y-Intercept, let fx=0:
2%280%29%2By=-11
red%28y=-11%29

Then following our Slope-Intercept Form, y=mx+b
2x+y=-11 -----> y= -2x-11,
where
Also, y-Intercept,b=-11


As we see the graph,


As we would see the Slope in green points, a movememnt of -2 on the y-axis (from the y-Intercept)
and +1 on the x-axis.

Starting point (0,-11):
On x -axis,0%2Bred%281%29=1
On y-axis, -11%2Bred%28-2%29=-13
Next point, (1,-13)

Again, on point (0,-11):
On x-axis, 0-red%281%29=-1
on y-axis, -11-red%28-2%29=-11%2B2=-9
Next point, (-1,-9)

Next, on point (-1,-9):
On x-axis, -1-red%28%2B1%29=-2
On Y-axis, -9-red%28-2%29=-9%2B2=-7
Next point, (-2,-7)

....Just continue on the succeeding points.
