\star\bigstar\star Parallel lines have the same slope. Remember, parallel lines never intersect. Lines with the same slope, but different y-intercepts will not intersect.


\star\bigstar\starNow, we have the slope of the line and a point that it passes through.

We can use the Point-Slope Formula:


\huge\boxed{\bf{y-y1=m(x-x1)}}

Remember, y1 is the y-coordinate of the point, m is the slope, and x1 is the x-coordinate.

Plug in the values:

y-(-8)=1(x-(-10)

y+8=1(x+10)

y+8=x+10

y=x+10-8

y=x+2


\huge\boxed{\mathbb{ANSWER:{\boxed{\bf{y=x+2}}}}}


\star\bigstar\star I hope it helps you!
