Answer:
The y intercept is (0,1)
The equation of the line is y = -1/2x+1
Explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -1/2x+b
Substituting the point
2 = -1/2(-2) +b
2 = 1 +b
Subtract 1 from each side
1 =b
The y intercept is (0,1)
The equation of the line is y = -1/2x+1
