Answer:

[tex]y=-\frac{2}{3}x-\frac{10}{3}[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

  • Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is 0)
  • Parallel lines always have the same slope

1) Determine the slope (m)

[tex]y =-\frac{2}{3} x +4[/tex]

In the given equation, [tex]-\frac{2}{3}[/tex] is in the place of m, making it the slope. Because parallel lines always have the same slope, the slope of the line we're currently solving for is [tex]-\frac{2}{3}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-\frac{2}{3}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-\frac{2}{3}x+b[/tex]

Plug in the given point (-2,-2) to solve for b

[tex]-2=-\frac{2}{3}(-2)+b\\-2=\frac{4}{3}+b[/tex]

Subtract [tex]\frac{4}{3}[/tex] from both sides to isolate b

[tex]-2-\frac{4}{3}=\frac{4}{3}+b-\frac{4}{3}\\-\frac{10}{3} =b[/tex]

Therefore, the y-intercept of the line is [tex]-\frac{10}{3}[/tex]. Plug this back into [tex]y=-\frac{2}{3}x+b[/tex]:

[tex]y=-\frac{2}{3}x-\frac{10}{3}[/tex]

I hope this helps!
