==> Find the slope. Using points (, ) and (, ), the equation for slope (m) is
Simplify:
Add:
Simplify/Divide:
So, the slope of your equation is 1.
==> Next, find the equation of the line by plugging in the slope and coordinates of one of the points in to point-slope form, or . For (, ), I am going to choose (-9, -9), but you could also use (2, 2).
Simplify:
Since 1*a = a, you can simplify 1(x + 9) into just x + 9:
Subtract 9 from both sides:
That is in y = mx + b form, as it can also be seen as y = 1x + 0.
