Answer:
The slope intercept form of the line is y = -x - 7
Explanation:
In order to find this, we start by noting that the slope will be -1. This is because parallel lines have the same slope. Now that we know this, we can use that and the point in point-slope form to get the equation. Then we can solve for y.
y - y1 = m(x - x1)
y - 3 = -(x - -10)
y - 3 = -(x + 10)
y - 3 = -x - 10
y = -x - 7
