How do you graph #3x - 2y = 6# by plotting intercepts?
Solve for the intercepts and find your two intercept points of y-intercept =
When we plot a graph using intercepts, we are being given 2 points: (0,?) and (?,0) - I'm using the very un-math-like ? to take away a little formality here! We substitute in the two points (or as much as we know about each point), then solve for the other part.
Let's do the y-intercept first. We know that where the graph passes through the y axis,
So that's one point
Let's do the x intercept. Following the same reasoning as before, we know that
And that's our other point
Plot those 2 points, connect them with a straight edge, and you'll get your graph.
