In the equation y = mx + b, where m represents the slope and b represents the y-intercept, we can determine the slope of the line to be -3. When two lines are parallel, they have the same slope (m).
To find the value of b, we need to substitute the coordinates of a point the line passes through into the equation. In this case, the point is (0, 2).
By plugging in the values, we get:
2 = -3(0) + b
2 = 0 + b
2 = b
