Answer:
The answer is in the photo.
Step-by-step explanation:
Slopes are represented using:
y = mx + b
_______
m - the slope, represented by a fraction or whole number
x - x, don't plug in the x-value
b - where you start on the y-axis
_______
On the left is the original slope. You apply the same slope to (5,-1). You don't have to apply the b.
So, all you have to do is start at (5,-1) and apply the angle, going up 8 and right 3.

Easy for a calculator. If you're not using a calculator, it's much more tedious!
There is an inverse sine key on your calculator, but you may have to press a key (likely labeled 2nd or INV) first. The attached image shows a TI-83 display. To get the inverse sine, I first pressed the yellow 2nd key, then the sin key.
Check MODE first to make sure you're measuring angles in degrees (if that's what you want!). Some calculators display angle mode with a small letter at the top of the display, D, R, or G usually.
The left side of the equation produces just x.
