To find the y-intercept, substitute 0 in for x to get y=12. Similarly, for the x-intercept, substitute 0 in for y to get x=-2. You can look at the following graph to see if the line passes through (-1,6), but it's much easier to just substitute -1 for x into the equation to get y=6. Therefore, the line does indeed pass through that point. Here's the graph: graph%28300%2C300%2C-5%2C5%2C-2%2C15%2C6x%2B12%29
