Part B.
Slope is -1/2& (-2, 2) is on the line
Y-Intercept:
Equation of the line:

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
