Answer:
x + y - 2 = 0
Explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept.
Put the given y-intercept b = 2 and the coordinates of the point (1, 1) to the equation:
subtract 2 from both sides

The equation of a line:

The general form of an equation of a line:

Convert:
add x to both sides
subtract 2 from both sides
