2x%2B3y=-6

%282x%2B3y-2x%29%2F3=%28-2x-6%29%2F3

You can identify a point and a slope and from these make the graph.

Please provide all instructions that go along with the equation.

I'll assume you want to graph this. If so, then we can replace x with 0 to find y.
2x + 3y = -6
2*0 + 3y = -6
3y = -6
y = -6/3
y = -2
Therefore (x,y) = (0,-2) is a point on this line. It's the y intercept.

Now let's plug in y = 0 to find x.
2x + 3y = -6
2x + 3*0 = -6
2x = -6
x = -6/2
x = -3
The x intercept is located at (-3,0)

Plot (0,-2) and (-3,0) on the same xy grid. Draw a straight line through the two points. Extend the line as far as possible in both directions.

Desmos and GeoGebra are two graphing tools I recommend.

If you wanted to solve for y to get into slope-intercept form, then,
2x+3y = -6
3y = -2x-6
y = (-2x-6)/3
y = (-2x)/3 - 6/3
y = (-2/3)x - 2

It fits the y = mx+b template
m = -2/3 = slope
b = -2 = y intercept
