27-11=16
--------- ___
3-1= 2
(simplify to 8)
the slope is 8 and you use the equation y2-y1 over x2-x1 (basically you subtract 2 of the numbers under the y column and 2 of the numbers under the x column) and your y-intercept with always be the number under y that matches up with the value of 0 under x, your y-intercept would be 3)
this makes your equation:
