You want to find the equation for a line that passes through the point (7,6) and has a slope of .

First of all, remember what the equation of a line is:

y = mx+b       Where:
  • m is the slope, and
  • b is the y-intercept
To start, you know what m is; it's just the slope, which you said was . So you can right away fill in the equation for a line somewhat to read:y=x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:
  • (7,6). When x of the line is 7, y of the line must be 6.
