Answer:

y=\frac{1}{2} x-5

Step-by-step explanation:

Slope-intercept form:

y=mx+b

where:

  • m is the slope
  • b is the y-intercept
  • x and y are corresponding coordinate points

When two lines are parallel, their slopes are the same. Mak a new equation with the same slope:

y=\frac{1}{2} x+b

Now we need to find the value of b. Insert the given point for x and y:

-4=\frac{1}{2} (2)+b

Solve for b.

Simplify multiplication. Follow the rule \frac{a}{b} *c=\frac{ac}{b}:

-4=\frac{1*2}{2} +b\\\\-4=1+b

Isolate the variable. Subtract 1 from both sides:

-4-1=1-1+b\\\\-5=b

The y-intercept is -5. Insert, replacing the "+":

y=\frac{1}{2} x-5
