Answer:

y + 5 = -2(x + 10)

Step-by-step explanation:

To make the line parallel, we need the same slope as the line. Because it is in slope-intercept form, we know that the slope, or [tex]m[/tex], equals -2.

Also, because we have the point that it passes through, we have enough information to put the values into point-slope form, which is:

[tex]y-y_{1}=m(x-x_{1})[/tex]

y + 5 = -2(x + 10)

The reason I made the subtraction signs to addition signs is because a negative times a negative equals a positive.
