So i know how to do this im confusing my self > n<me graph the linear equation. 2x+6y=−6

see the attached graph

Step-by-step explanation:

When an equation is in standard form (or almost standard form), I like to put it into intercept form for graphing. Here, it is convenient to divide the equation by 2 to put it in standard form (coefficients mutually prime).

  x +3y = -3

Now, it is convenient to divide by the constant on the right (-3) to put the equation into intercept form:

  x/(-3) +y/(-1) = 1

The denominators are the x- and y-intercepts, respectively. Plot those, (-3, 0) and (0, -1), and draw the line through them.
