Answer:
y = -x + 2
Explanation:
The y-intercept, b, is 2 since that is where the line intersects the y-axis.
The points (0, 2) and (2, 0) are on the line.
To go from (0, 2) to (2, 0), start at (0, 2).
Go 2 units down. This is a rise of -2.
Then go 2 units right. This is a run of 2.
slope = rise/run = -2/2 = -1
The slope, m, is -1.
y = mx + b
y = -x + 2
