Question 136344
You can start by getting your equation into the slope-intercept form: y = mx+b
{{{x+2y = -6}}} Subtract x from both sides.
{{{2y = -x-6}}} Divide both sides by 2.
{{{y = (-1/2)x-3}}}
Now you need only two points to draw the graph of a linear equation.
First. let x = 0 then solve for y.
{{{y = (-1/2)(0)-3}}}
{{{y = -3}}}
First point is (0,-3)
Now let y = 0 and solve for x.
{{{0 = (-1/2)x-3}}} Add 3 to both sides.
{{{3 = (-1/2)x}}} Multiply both sides by -2.
{{{-6 = x}}}
Second point is (-6, 0)
Now plot these two point on your graph paper and draw a straight line through them. You should get the graph shown here:
{{{graph(400,400,-8,5,-5,5,(-1/2)x-3)}}}
