I'm assuming that you probably meant to write:
y = x+7
y = -4x + 2

To solve by graphing, just draw the graphs and see where the two lines cross. If you need additional help obtaining the graphs of these lines, I wrote three lesson plans for algebra.com on graphing a straight line. These are both in slope intercept form so graphing the lines should be easy.

The first line has a y intercept of 7 and a slope of %28rise%29%2F%28run%29+=+1%2F1.
The second line has a y intercept of 2, and a slope of %28rise%29%2Frun%29+=+%28-4%29%2F1. They should look like this,
graph%28400%2C400%2C+-10%2C10%2C-10%2C10%2C+x%2B7+%2C+-4x+%2B2%29

Notice that the lines cross at a point where x = -1, and y =6. Therefore, the solution is the point (-1,6).
