Answer:
y-intercept: 1
equation of the line: y= -1/2x +1
Step-by-step explanation:
y=mx+b
1. plug in slope
y = -1/2x +b
2. plug in the given point
2 = -1/2(-2) +b
3. that gives 2=1+b
4. subtract 1 on both sides
2 = 1 +b
-1 = -1
5. that gives 1=b
7. then plug in b for the equation y=mx+b and use the same slope
y= -1/2x +1
