How to graph the linear equation?
Here we want to graph the linear equation:
x + 2y = -1
To do so, we need to find two points that are solutions to the equation, to find the points, just evaluate the equation.
when x = 0 we have:
0 + 2y = -1
y = -1/2
When y = 0
x + 2*0 = -1
x = -1
So we have the points (0, -1/2) and (-1, 0). Now plot these two points in a coordinate axis and connect them with a line.
